I have no idea why she's doing it, but she will whinge and whinge about going to the toilet every 5-10mins throughout the day (if she doesn't have access herself - say if we're out). It's driving me INSANE!!
She does wee everytime she goes... sometimes it's a fair bit other times it's not a lot (although I don't go with her all the time).
She doesn't seem constipated, she doesn't mention pain or anything when she urinates, she hasn't had any blood that I've noticed.... I've been thinking this is a learned behaviour but my Mothercraft Nurse Mum mentioned about her ridiculously frequent trips to the toilet and didn't think it was normal.

She's currently calling out "daddy I need to go to the toilet". It's 9.05pm and she's been to the toilet 3 times since 8.30pm. This happens EVERY night. I try ignoring her and it doesn't work. We take her and let her go but she only needs to go again 5 minutes later. I've tried limiting her fluid intake before bed, upping her daily fluid intake. Watching what she eats. Letting her eat what she wants. Asking her to go to the toilet before bed, not telling her to go (in the hopes that her bladder will be so full that she goes all at once and then has no more need to go). I've tried everything but locking her in her room and letting her wet herself. She's been toilet trained for over 6 months and is 30months old.
This behaviour is getting old now. She's waking several times a night and screaming out for her Dad to take he to the toilet (yes she can go on her own.... :S). We can't leave her to scream and take herself because we have had family staying for the last 11 weeks and it wakes them up.
My son is lucky to go once a night. She can go anywhere from 4-10 times a night. It's driving us batty. We're not getting the quality sleep we need and neither is she.

I'm now worried that something may be wrong? Even at playgroup where she is heavily distracted she goes to the toilet at least 6 times in 1 and a half hours and everytime something comes out.

HELP!! Does this sound familiar to anyone? Should I be taking her to see someone?
