I'm worried dd 2.2yo has a uti. All day when she's had a wee she's expressed discomfort, she was having nappy free time and wee-d on a towel she was sitting on and it smelt offensive and just now she's told me her vagina hurts. What I can see looks very red. I'm going to call the gp in the morning for an appointment but presumably they'll need a urine sample? she is in nappies and refuses to sit on a potty. She's wee-d on the loo once but it was more of an accident, certainly she won't do it on command! How do I get a sample? I don't want to waste anymore time than necessary, if she needs antibiotics then I'd want them to start ASAP but have no idea how to get the sample. Any tips?
