almost 3 year old decided he doesn't want to go in the potty anymore

Hello! I have a DS who is 2.11 and we have been potty training about 2 weeks after 2 previous failed attempts where he simply wasn't ready. Last week he had 2 and half days (almost) perfect where he would tell me he needed a wee and I would take him to the toilet. Lots of praise and he got to flush the toilet which he loves. After those 2 and half days he simply decided he wasn't going to tell me he needed a wee anymore and started going In his pull ups. 5 days later and he is still wet ring himself. I have put him I pants now so he knows he is wet, but e doesn't care. I know he can do it as he did it last week, so I feel he is just being lazy. He went back to playgroup today where he has been off for 3 weeks over Easter and they said he did 3 wee's on the toilet, just 1 accident. Where do I go from here? I feel like if I put him back in nappies I am just allowing him to be lazy and its not the case of him not being ready. TIA.
