My three-and-a-half-year-old son was potty trained a year ago and was able to wear underwear for 5 or 6 months before regressing. He is constantly peeing his underwear so I switched to pull-ups, which he hates, however he continues to pee in these as well. He shows no motivation for wanting to be a “big boy” again. I’ve been trying to wait him out but it’s been a long time, 6 months. What else can I do?
Otherwise, you have two options. Option 1 is to accept his wearing pull ups and don’t worry. He will eventually decide to get out of pull-ups and pee in the toilet.
The other option is to increase his motivation to have dry pants. To increase motivation, you can try a “No more pull-ups” chart. Try to get him involved in setting it up. Start with rewarding him with a sticker every time he tinkles even a bit in the toilet. Set it up so he wins and gets enough stickers to exchange for a small treat or privilege every day. After a while, you can switch to “dry pull-ups” for a small period of time (an hour or two) as the target for getting a sticker. Then, when he gets to be dry for a period of time, switch him to underwear and continue the chart. Make the criterion easy enough for him to win but gradually increase it. Use praise as well as the stickers.
I would advise against criticism, punishment or even taking away stickers at his age.
