Potty training is one of the few developmental milestones where the family and the daycare are equally involved, and where coordination matters more than method. The same child who pees on the potty cheerfully at home can refuse it at daycare for a week, and the same child who never sits at home will go on cue when the lead teacher asks. The work, mostly, is keeping the two environments in sync.
This guide covers what daycare staff actually do during potty training, how to know when your child is ready, how to coordinate the start date, what to pack, how accidents and regressions are handled, and the policy questions that catch families off guard. For the related question of when daycares require daytime training before preschool entry, see our potty training age at daycare guide.
The AAP frames potty training around readiness signs, not a calendar age. Most US children show readiness between 18 and 30 months, with full daytime training typically complete between 2.5 and 3.5 years. Boys are commonly six to eight weeks later than girls on average, and the range within each child's group is wide. The AAP and the CDC explicitly recommend against starting before the child shows readiness signs, regardless of social pressure.
Look for several of these at home before bringing it up with the daycare:
Most centers prefer that potty training be parent-initiated and parent-paced. They follow your lead, not the other way around, and most centers have a written protocol for how they support the family's plan. The simplest opening conversation is a short note at pickup or in the daily-report app: "We are starting potty training this weekend. Can we sync on Monday on how to keep it going at school?"
A productive coordination meeting covers:
Most licensed centers in 2026 follow some version of the AAP-aligned protocol. Specifics vary, but the bones look like this.
The teacher offers the potty as part of the routine: after waking, before meals, after meals, before outdoor time, and before nap. Most centers do not pressure children to sit. A child who refuses is invited to try again at the next transition.
Once your family has decided to commit, the center will move your child into underwear or training pants for the daycare day. Three to six pairs of extra underwear and at least two full changes of clothes go into the cubby on day one. Many centers ask families to send shoes that can be wiped down, because accidents are inevitable in the first week.
Accidents are documented in the daily report. Most centers do not announce them in front of other children. A good policy treats accidents matter-of-factly: clean clothes, brief acknowledgement, return to the activity. Centers that shame children or charge a "laundry fee" for accidents are operating outside AAP and NAEYC guidance.
Most centers keep children in pull-ups for nap during the early training weeks even after daytime underwear is established. Overnight dryness is a separate developmental skill that typically follows daytime dryness by six to eighteen months.

Regressions are normal. They show up most commonly during big life changes: a new baby, a room transition at daycare, a move, a parent traveling, or an illness. The AAP recommends treating regressions calmly, returning to whatever support level worked previously, and not framing the regression as a failure.
A short pause, a return to pull-ups for a week or two, and a quiet restart almost always works. Daycares with experienced toddler-room staff have seen this hundreds of times and are usually a calming influence; ask them what they see most often.
A few specific policies are worth confirming before the first underwear day.
One thing that does not work: waiting for the daycare to take the lead. Centers will support your plan and reinforce your routine, but they cannot start the process for a child who is not ready at home. The reverse is also true; a child trained at home will usually transfer to the daycare environment in two to four weeks with steady reinforcement.
For children with constipation, urinary urgency, sensory sensitivities, autism, or motor delays, talk to your pediatrician before starting. Many of these children train successfully, but the plan is different and the timeline is longer. Daycares are legally required under the ADA to provide reasonable accommodations, which can include extended diapering past the typical age cutoff. Documentation from your pediatrician makes the conversation easier.

Some children consistently wait until pickup to go. This is more common than parents realize. It is not a sign of a problem at daycare; it is usually a signal that the child finds the home bathroom safer, or that the daycare bathroom has a different sensory profile (different lighting, different toilet height, different paper). Ask whether the center has step stools, footrests, and child-height toilets; the more "home-like" the bathroom, the less holding parents report.
If the holding leads to constipation or urinary discomfort, loop in your pediatrician.
Potty training works best when families and daycares move together and slowly. Watch for AAP readiness signs at home, open a clear conversation with the lead teacher, pack more than you think you need, and treat the first two weeks as data collection rather than a deadline. The actual timeline rarely matches anyone's plan, and that is fine.
