I'm off for DS5's 4 month immunizations tomorrow and will ask the nurse then but thought I might ask for some opinions now. He has just turned 4 months but weight and height is that of a 6 month old (a bit more actually) and he is exclusively breastfed at the moment. I'm wondering what the thought is of trying him with a bit of food? He feeds at 8am, 11am, 1pm, 4pm, 6:30pm and then 10ish and usually once or twice during the night. So what do you think should I offer some solids at some point throughout the day?
