How long does it take for your baby to feed? Chantelle is bottle fed and it takes her 1/2 hr to drink 150- 180mls. I thought she would be quicker. (I seem to remember my son taking only 10 -15 mins at the same age). She is using the pigeon peristalic teats Y cut which are variflow but she goes no faster than when she was on the newborn one. Any suggestions?
