How old is your baby? I haven't heard you have to cut the pinks in half even for new born baby's. I'd only make sure the pinks you feed are small, as in day or 2 old. For our baby that was about a month old we fed her 1 small pink every 5 days, she is about 3 months old and I just moved her up to 2 pinks and soon will be trying fuzzies. I don't think it would hurt to try a full pink and see how your baby handles it. If you end up with a regurge, wait the 10 day regurge protocal then start again with the half pinks.... JMO
