My dd, aged two and half has been doing runny, yellow poos....you know the type of thing since Sunday, but she only seems to do one a day. On Monday she did do 3 in one hour, but thats its. She goes all day fine then between 4-5pm there it is. She is totally fine in herself and is behaving normally and sleeping the same amount. The rest of us are fine. Ive not been starving her or anything, just feeding her what we normally would. Should I be worried or just let it take its course. I was wondering if this is just the nature of the bug that is going around.
