Open to all advice as it’s been a year. My son is 3 and very bright - he potty trained a year ago within 2 days. No accidents and no problems; just wanted to do it and asked and that was it. After a couple of weeks we removed the potties snd transitioned to the loo with the small seat insert and step. We have 4 toilets in our house. He will only use my pink one, upstairs. That’s it. If we go out he holds it all day. If he goes to nursery he holds it all morning. There is nothing in a year that will convince him to use another loo than mine. He obviously won’t put a nappy on so when we have gone on holiday he either holds it until he poos himself or just poos/wees when he gets into the bath. I really, really don’t know what we are supposed to do about this. I’ve tried telling him my loo was broken. He caved eventually and used another one in the house. Once. Then he had an absolute meltdown and refused to go again and was screaming/holding it all day and was clearly in discomfort so I had to give in and let him back on my one.
Will he just grow out of it?! His reason is just that he likes my bathroom and that’s it! But I feel so sorry for him holding it in all day and it’s really stressful when we go on holiday! I’m also dreading him starting school next September as he surely can’t hold it every day all day.
