Why does my toddler only want one parent?

It’s very common for toddlers to strongly prefer one parent for a while. This can be a normal developmental phase, especially in the 1–3 year range, as toddlers become more independent, test boundaries, and lean toward the parent who feels most predictable or soothing in a given moment.

Why it happens:

• Your toddler may be asserting autonomy and control.
• They may want the parent linked with comfort, routines, or fun activities.
• They may be more attached to one parent during certain parts of the day, like bedtime or when they’re tired, upset, or overstimulated.
• Sometimes it’s simply a phase that comes and goes.

How to handle it:

• The preferred parent can gently step back at times so the other parent has chances to connect.
• The less-preferred parent should keep showing up calmly, warmly, and consistently.
• Use short, calm validation with a boundary: “I know you want Mommy, but Daddy is helping you right now.”
• Create small one-on-one routines or rituals with the less-preferred parent.

What to avoid:

• Don’t take it too personally if you can help it.
• Avoid anger, pressure, or guilt-tripping.
• Try not to turn it into a power struggle.

When to check in with a pediatrician:
If the preference is sudden, extreme, or comes with other concerning changes such as regression, intense fear, withdrawal from both parents, pain, sleep changes, or a big shift in behavior, it’s worth asking your pediatrician if something else could be going on.
