My dd had a tummy bug 2 weeks ago, nothing major but her tummy was upset. Since then it hasn't gone back to normal, she often complains of tummy ache, poos 4/5 times a day, quite loose most of the time & is very windy. Been to gp's & he said it may take a while to revert back to normal. Wondering if probiotic yoghurts might help revert to normality. She is getting quite distressed by it so would like to try something.
