10 mo DS has had sickness / diarrhoea for the past 6 days. He's very listless and lethargic. Called the doctor, who just said we had to wait it out. DS has been eating only ready brek and banana all week (as well as being breastfed). He was already on the thin side (15th centile and issues earlier with dropping down the centiles). He's now looking distinctly skinny and I'm assuming he's lost a bit of weight. A bit worried about this and wondering if anyone has any ideas for things to feed a sick baby and get him back on the road to recovery. Or do I just have to wait it out and accept he's going to lose quite a bit of weight before he gets better ?
