I have encountered this kind of experience many times
with my old Baby Alive dolls.
The same thing usually happens.
The water or doll food is coming out from certain parts of the Baby Alive body
after or while feeding.
The leaks usually come from underarms, legs, necks and speaker holes.
When anything like this happens, I will open the doll and see what's inside.
Normally, I will see the broken tube here and there, hence the leakage.
what I usually do to fix this problem.
