Help! Been potty training DS 3 for the past couple of months, he's done really well and now only has an accident or 2 a week. So in the beginning we did a reward chart and chocolate/ edible treat if he'd done well. He cracked wees very quickly this way. Poos was a lot of hard work, and a couple of weeks of washing out poo-y pants 2 to 3 times a day (and washing DS!) nearly broke me. DS did not care about being dirty. I researched endlessly and realised poos are a lot harder to learn. DH then had the idea to up the reward stakes with mini Thomas toys for very poo on the potty/ loo (he's Thomas mad.) within a few days we had a break through, and we've had a 90% success rate for the last month. But, we've spent £60/£70 on these toys and our house is getting over run! As soon as he's done his poo he asks for his Thomas 🙈 for info he's not worried about having a poo, goes at home and out, no other issues. I just need help to stop the cycle now without him getting lazy and deciding not to use potty/ loo. I have 1 Thomas left in the house and no chance of buying any tomorrow! I tried to tell him mummy doesn't have any left but he just said I could buy more, cheeky monkey. I wondered about moving to a weekly larger treat, but I don't know if he's going to manage that. Help?! Advice?! Please?!
