We are in the process of potty training my 3 year old son (3 years and 3 months). Last weekend we did 2.5 mostly naked days and it went great. He only had two misses. Come Monday he had to go to school & they do not have a little potty there. He refuses to go in the regular toilet so I put him back in diapers at school because I don’t want him to get traumatized. So he’s in diapers at school and underwear at home (except at night but he is waking up dry!) which is working fine but I’d like to get him using the regular toilet so he eventually wear underwear at school. Any tips to encourage it? We’re already bribing with m&ms as well as toys & phone time. Nothing has worked yet.
