I have a Nuk 5 bottle that I got from baby-pants but, I have a problem with it and was wondering if someone could help me!
The problem is when I got it there was no hole in the nipple part. So I made some small holes with a pin but it don't seam to be working..
When I tried to suck harder it just sucked in the nipple part in and then all my juice was leaking out...
Has anyone else bought one? What did you do to make a hole in the nipple?
