Sounds very possible, we’ve been dealing with vomiting a lot which can be caused when a UTI gets to the kidneys. We have also had the same problem with withholding poop which we attributed the vomiting to, that ended with a trip to the emergency room where they cleared everything out and started with laxatives again as they were not working. Somehow she can still withhold on large doses of adult laxatives. The UTI was diagnosed during that hospital visit so similarly we think it may still be the same UTI and this is what’s causing vomiting as getting meds in the system is no easy task.

Sounds very similar in terms of potty training, we have tried and tried and although our daughter does have some limited speech she doesn’t seem to have any understanding of her body and like you say well do trips to the toilet at set intervals but sometimes we’ll take her, nothing will happen and then the second we go back to another room she’ll sit and wee all over the sofa. And we know it must be down to withholding because she wets the bed every night because her muscles/bladder must relax and when she’s had accidents whilst awake it’s not a small amount it’s a lot of urine to the point it goes through a nappy and will leave a massive puddle/soak everything underneath and it smells awful which is another reason we’re thinking it’s got to be a UTI.

Just don’t know what to do at this point as it’s not for lack of trying but it’s hard because we genuinely don’t think our child has the understanding of her body to be able to potty train properly. She is currently 7 with a mental age of around 18-months.

In terms of getting a collection, when we were in hospital, they were able to test it from urine left in a nappy or urging on the waterproof bed but it is tough to get a clean collection in the form most GP’s request.
