My friend has got an 8.5 month old boy who's always been quite an eater. He's had a bad cold and chest infection for a couple of weeks now, she's taken him to the doctors and he's now on antibiotics for the chest infection, but my friend's worried that her ds isn't eating any solids, he's back to breastfeeding every three hours including through the night when previously he was sleeping through. She's now worried that a) he's not getting enough of the correct nutrients and b)he's taken a big step back on the weaning front. She keeps offering him solids but he refuses them all, has done for two weeks now. What should she do, keep bfing and hope he starts being interested in them again or something else?
