Me and my kids are staying with my mom temporarily, I have a 4 year old son who showed very little interest in using the bathroom other then in a pull up. He starts kindergarten next year and won't be able to attend unless he is fully potty trained, which is understandable. So I made the decision to not put a pull up on him during the day, and only use one at night which also means I'm no longer buying the boxes just small packs, which is a savings. When I had told my mom my plan she did not object to it but just said ok. She does watch him while I work but anytime she takes him out she puts a pull up on him instead of him telling her he has to go to the bathroom. When I take him out I do not put one on him and he does just fine without. I do know this is not her responsibility to potty train him but it has gotten to the point he screams for a pull up. Quite frankly I am tired of buying them as they are extremely expensive, even the cheapest ones I can find.
I had posted something to specify some things in the comments so I'm just going to post it here and add some things...
So to specify some things, I did not just start potty training him I introduced him to the potty at 1 I bought him his own potty to get him use to sitting on it. At 2 was when I started to potty train full time with him wearing pull ups a timer set for every 30 mins and I would have him sit on it, and he hated it, would sit there crying and screaming only actually going in it a few times. So yes I did back off a little bit I didn't want to traumatize him.
While I don't pay her directly for babysitting I do pay for the groceries, do the grocery shopping, put gas in her car and pay whatever bills she wants me to pay for that month, I also do all the cleaning. Yes I know I should be paying some bills since me and my kids do live there i do not have a problem with that.
I do have other kids but they are not younger they are older, he is the youngest. I did not have any problems with them potty training so this is a first for me.
Me and their father are not together, he is not able to watch him while I work, for various reasons.
I have tried to find other childcare, there is a wait list which he is on several of them. I did not just expect my mom to watch him just because I am staying there.
