Parenting Plan for Infants and Toddlers: What's Different When Your Child Is Under 3
A parenting plan for an infant or toddler is fundamentally different from a parenting plan for a school-age child. Children under three are at the most attachment-sensitive period of their lives — what works for older children can be actively harmful for the very young. Here is what separating parents need to know.

The 50/50 schedules that work well for older children — week-on/week-off, alternating weeks — are usually not appropriate for infants and toddlers. Children under three need frequent contact with both attachment figures, but they cannot yet hold a parent in mind over long absences. Extended separations from either parent can cause genuine distress and, over time, can disrupt secure attachment.
This is not about giving one parent more time than the other. It is about recognising what the child's developmental stage actually requires. The plan should evolve as the child grows.
What Works for Infants (0-12 Months)
For very young infants, child development specialists generally recommend the primary caregiver maintains the longest blocks of time, with the other parent having frequent shorter contact periods that build relationship without requiring extended separations. Many families use daily or near-daily contact with the non-resident parent in this stage — short visits of two or three hours, gradually extending as the child grows.
Overnight contact at the non-resident parent's home is typically introduced gradually, not all at once. The exact age at which overnights are appropriate is debated among specialists, but most recommend they begin in the second year of life, building from occasional to regular.
What Works for Toddlers (1-3 Years)
Toddlers can handle shorter blocks at each parent's home, but still need frequent contact with both. The 2-2-3 schedule (two days with one parent, two with the other, three with the first) is widely used. So is the 3-3-4-4 schedule for slightly older toddlers. The principle is the same: no child should go more than three days without seeing either parent.
Geography matters enormously. Frequent transitions are only practical if both parents live close to each other and to the child's daycare or childminder. If parents live further apart, longer blocks with more video and voice contact between visits may be necessary.
Turn this schedule into a written agreement
A schedule only reduces conflict once it is written down. The Parenting Agreement Template covers the schedule, holidays, exchanges, decision-making and communication — fill it in today and both of you know exactly where you stand.

Beyond the schedule itself, your plan should address: feeding and sleep routines (consistency between homes matters more here than at any other age); transition rituals to ease the child's adjustment; communication between the parents about how the child has slept, eaten, and behaved; and a clear review date — under-three plans should be revisited every six months as the child develops.
Building In Flexibility for Developmental Changes
The single most important clause in an under-three parenting plan is the review clause. A plan written for a six-month-old will need significant changes by the time the child is eighteen months, and again by three years. Build in a structured review at six-month intervals so neither parent feels they are renegotiating from scratch each time.
Which Schedule Suits an Infant or Toddler?
For the youngest children, frequent contact and short separations matter most — which is why the 2-2-3 schedule is the usual starting point, with overnights introduced gradually. As your child grows you will move toward longer blocks.

Getting Legal Advice
Parenting plans for very young children are an area where it is particularly worth getting specialist family law advice. The schedule choices you make now will affect attachment patterns that show up years later. A family law attorney with experience in young-child arrangements — ideally working alongside a child development specialist — can help you build a plan that protects your child's relationship with both parents while respecting the developmental stage they are actually in.
