I'm confused what to do. Spoken to GP about baby having frequent episodes of vomitting and other symptoms and he's said it's due to overfeeding. He's breastfed then topped up with formula when needed during the day and bottle fed through the night. I don't know whether to express and feed him so I can monitor what he's having? He hasn't told me what he should be having just he thinks I'm overfeeding him. Also debating changing his formula as he said the next step is to use a thickner so looking at a thicker formula such as cow and gate comfort milk?
