My Baby Only Wants One Parent
The short answer
Parent preference is one of the most common and emotionally painful behaviors in babies and toddlers. It is a completely normal part of attachment development and is not a reflection of who is the "better" parent. Babies and toddlers typically cycle through phases of preferring one parent, and the "rejected" parent's consistent, loving presence during these phases actually strengthens their bond over time.
By Age
What to expect by age
Young babies may show a natural inclination toward the parent who does the majority of feeding and caregiving, often the nursing mother. This is driven by scent, voice familiarity, and association with food - not by love. The other parent can strengthen their bond through skin-to-skin contact, being the one to do baths or bedtime, and spending focused one-on-one time with the baby. Preference at this age is about familiarity, not rejection.
As separation anxiety develops around 6-9 months, parent preference often becomes more intense and obvious. A baby may cry or reach for one parent when the other tries to hold them. This can feel devastating for the non-preferred parent, but it is actually a sign of healthy attachment development. The baby is demonstrating that they understand who their primary attachment figure is. The non-preferred parent should continue to be present, warm, and involved - not withdraw.
Toddlers are famous for parent preference that can change suddenly and without warning. Your toddler may insist only mommy can give baths for three months, then switch to demanding daddy exclusively. This is normal and driven by their developing sense of independence and control. Allowing the preferred parent to handle some tasks while the other parent builds their own special routines and rituals helps maintain both relationships.
Parent preference may continue but often becomes less absolute. Toddlers in this age range can begin to understand that both parents are available and each offers something special. If one parent is consistently rejected despite being consistently available and loving, and the child seems genuinely distressed (not just preferential) with that parent, it is worth discussing with your pediatrician to rule out contributing factors.
What Should You Do?
When to take action
- Your baby or toddler goes through phases of preferring one parent and it shifts over time
- Your child prefers the parent who is more available or who handles most caregiving tasks like feeding and bedtime
- The preference is stronger when your child is tired, sick, or in an unfamiliar environment
- The "rejected" parent can still comfort the child when the preferred parent is not available
- Your child seems genuinely fearful or distressed with one parent (not just preferential), showing signs of anxiety such as trembling, freezing, or avoiding eye contact with that parent specifically
- Parent preference is so extreme that the non-preferred parent cannot provide any care even when the preferred parent is unavailable, and this has persisted for many months
- The "rejected" parent is experiencing significant depression, feelings of inadequacy, or is withdrawing from the child as a result
- Your child shows sudden fear or avoidance of a parent or caregiver they were previously comfortable with, especially if accompanied by changes in behavior, sleep, or mood
- The family situation has become so strained by parent preference that it is affecting the mental health of one or both parents or the overall family dynamic

Related Behavior Concerns
My Toddler Is Aggressive Toward Pets
Toddlers being rough with pets is extremely common and almost never reflects true aggression or cruelty. Young children lack the motor control to be consistently gentle and do not yet understand that animals feel pain the way they do. With patient, consistent teaching about gentle touch and close supervision, most toddlers learn to interact safely with pets by age 3-4.
My Baby Doesn't Seem Attached to Anyone
By 7-9 months, most babies show clear preferences for their primary caregivers and some wariness of unfamiliar people. If your baby seems equally comfortable with everyone and shows no distress when separated from caregivers, it may simply reflect an easy-going temperament. However, if combined with other social differences, it can occasionally warrant further discussion with your pediatrician.
My Baby Arches Their Back
Back arching is very common in babies and usually a normal way of expressing frustration, discomfort, or just stretching and moving. Most babies arch their backs when upset, tired, or trying to see something. However, persistent arching with crying, especially during feeding, can be a sign of reflux or discomfort that should be discussed with your pediatrician.
My Baby Grinds Their Teeth
Teeth grinding (bruxism) is surprisingly common in babies and toddlers, affecting up to 30% of young children. Most children grind their teeth as they explore their new teeth or self-soothe, and the vast majority outgrow it completely by age 6 with no lasting damage to their teeth.
Baby Not Playing Independently
Needing a lot of parental interaction during play is completely normal for babies and young toddlers. Independent play is a skill that develops gradually, and expecting too much too soon can backfire. Most babies under 12 months genuinely need your presence to feel safe enough to explore. By 18-24 months, short stretches of independent play (5-15 minutes) begin to emerge, gradually lengthening through the toddler years. Your child is not spoiled or overly dependent - they are doing exactly what developing brains are designed to do.
Baby Separation Anxiety at Daycare
Separation anxiety at daycare drop-off is one of the most common and heartbreaking experiences for parents, but it is a completely normal and even healthy sign of secure attachment. It typically peaks between 10 and 18 months and can resurface during transitions. Most children stop crying within 5-10 minutes of the parent leaving and go on to have a good day. This phase is temporary, and it does not mean your child is suffering or that daycare is the wrong choice.
