So perhaps this has been answered but I couldn't find exactly the situation. My son is 4 and a half months and 7.5 kg and 99% height. Although I heard size doesn't really matter. He has started eating 8-9oz per feed at first only 6 bottles a day and STTN. Lately he's after at least 8 bottles screaming for food every few hours. The Hv said to add some solids 'if it seems like milk isn't enough' I'm agonising over it a bit. I heard it can cause gastric issues later on and excema (which my dh has and I m ow how horrible it can be) Hv confused me a bit by saying 'don't do it if you don't have too... Its safe if you do but there is a slight risk of gastric issues'. I don't know what to make of it. I should say I suffer a bit from a lingering PN anxiety so I don't know if this is another silly worry or I should keep holding on till he's a little older.
