my 18 week old dd seems ready for weaning, she is drinking 9oz of aptamil (number 1) every 3-4 hours, she is chewing everything she canmanage to get to her mouth, chewing her tongue, she has started waking in the night to feed when she has previoously slept through til now, and whenever we eat she starts screaming...what do i do put her on hungry baby aptamil or introduce some baby rice?
