So we have been potty training for over a year now and we're still not successful! My son turns four in a week so all advice appreciated!

Backstory: last April my son was nearly fully potty trained. Then, In the same week, his (amazing) daycare teacher left and his little brother was born. Since then, we've never been fully successful with being potty trained for poop. We'll have weeks where things seem fine and like he's trained and then a total regression!

I have tried: incentive charts, 3 day methods, pull ups, underwear, every 30 minutes sitting on the potty and probably more that I can't thing of now.

Someone please help! He's supposed to go to camp this summer but I can't send him if he keeps having poop accidents!
