My 7 month old son hasn't put on any weight for the past 5weeks. He's down to 3-4mouthfuls of food at each sitting and never manages more than 4-5oz milk (now only 3times a day) I've tried to interest him with finger food, different flavours, avoiding snacks between meals, to clapping and cheering every mouthful that goes in.His weight is fast falling to only the 9th centile on the growth charts, and I'm pulling my hair out, getting increasingly more frustrated with each meal that passes. He's started to wake up again at night, which is making me tired and even less patient. None of which is helping. Has anyone got any good ideas?
