My ds has just started to sleep through the night at 3 months which is great but i want to make sure he has enough food. He is formula fed and feeds 4 times now that he has lost his 3am feed. If i give him 3 7oz and an 8oz before bed then he should be getting enough for his weight but the carton only says about giving him 7oz even when he 6 months. Can his tummy handle 8oz? Sorry for rambling - first time mum!
