My 11 month old has dropped from 50th to 9th percentile having had what the doc now tells me 'was' pneumonia, but we were originally told chest infection. He has lots of flem on chest so keeps being sick when he eats, if he coughs. Any advice on getting his weight back up again. He is eating about half what he normally does but it's often coming back up again, particularly if he comes across a stray little lump. We are back to pureed home made baby food which feels like going backwards... and 3 7 oz bottles of stage 3 formula a day.
