My DD is 4 1/2 months old ff on aptimal, she has been teething badly for 3 weeks and the last week she is taking HALF her milk a day. I'm beside myself now, she's a small baby anyway Im worried she will get under weight. She is only 12 lb 12oz!!! She seems happy generally, considering the teething. So I don't suspect she is unwell.
Please only genuine help
