My son is almost 3 weeks old and I have to watch how much I feed him because he doesn't have a shut off switch! He will literally just eat and eat unless I stop to burp him and wait a good ten minutes so he can register that he's getting full. I'm worried about how much and when to increase his amount at feedings. He's currently eating between 2 and 3 oz every 3 hours.. I don't force him to stop eating but I follow his cues such as slowing down/getting sleepy. How should I approach increasing his intake without making him sick? A couple of days ago I let him eat 4 oz and he got a tummy ache and projectile vomited across the couch 😩 Tips for this FTM? ☺️
