I'm 30 weeks pg, DD was 3 in August, she feeds between 1 and 3 times a day.
For the past couple of days DD has been a poo-machine...
looser than normal, but not diarrhea. Last night she woke up at midnight with a nappy full 
no temp and eating fine, she hasn't anything out of the ordinary in the past few days, and is perfectly happy in herself, so I'm pretty sure she's not ill, but my colostrum did appear a week ago, it's not affected her desire to feed at all (nothing does affect DD's desire to "feed", not even there not being anything there for 4 months)
I have heard that colostrum can cause loose bowels in toddlers, anyone got experience of this? how long could it last? will her digestive system get accustomed to it? not sure we could be doing with this for another couple of months, but not sure what the alternative would be - stopping feeding DD is not an option, she's a total boob addict....
