Does this sound like a possible UTI?

My 18 month old DD had gastro last weekend with diarrhoea and at times overfilling her nappy with it! She recovered quite quickly from gastro but then a couple of days ago she started crying out of the blue and holding on to her nappy. Since then this has been a regular occurrence throughout the days. She will just suddenly start crying every so often and hold on to her nappy. And at night she keeps waking crying for a bit and then resettling (which is so unusual for her). She also suddenly hates being in the bath and having her nappy changed. Does this sound like a possible UTI? I wonder if some of the diarrhoea got into her urinary tract? Or maybe she's still tender from the diarrhoea? She doesn't have a temperature but she's just not her usual, happy, good sleeping self. :(

hmm not sure. Can you try giving her extra water to try flushing her system if thats what it is?

Worth taking her to the drs to get checked. A similar thing happened to my DD, she was intermittently crying and saying it hurt and grabbing her nappy, she didn't have a temp initially but got one about 5 days later, turned out she had a UTI and was promptly treated. The Dr told me a common cause of UTI's is dehydration, so given she has just had gastro she might have got a bit dehydrated and a bug got in.
If it is a UTI, better to get onto it sooner rather than later to save any kidney damage. It might be nothing, but no harm in doing a urine sample. (besides that fact it is an absolute pain to collect!)

I have no idea, but just sending a big hug for both you & M :hug: hope she feels better soon and you get to the bottom of it.
