My 3 week old son keeps eating himself sick. Help?!?

Burp more often. Give the feeds in small amounts, burp for a good ten minutes, give more formula. But it's common and normal for newborns to have a stomach valve that's not yet mature and doesn't close fully after feeding, resulting in some of the stomach contents coming right back up. It looks like a lot more than it is, since it's mixed with mucus, stomach fluids, and saliva.

Personally, other than burping more often, I'd simply feed him as needed. As long as he's gaining normally, the vomiting isn't an issue unless it goes on at least a couple months. I had to nurse two of my kids with the chair and floor around us covered in towels because it was a given that they'd projectile vomit after.

eta - Oh Lord, a childhood specialist would never be so uninformed as to say things like "some babies just can't digest breastmilk properly." If they have an incredibly rare condition that makes breastmilk indigestible, it would not only be immediately apparent, but they wouldn't be able to take formula either.

Spitting up is normal for young babies. But 'arching his back' suggests he may have reflux. He's also taking HUGE feeds for a 3 week old. If you had been able to breastfeed directly, he'd be taking around 2 ounces at a time, and that's really about all his tiny belly can hold.

And 5 hours is much too long, except maybe once at night. Again, a baby on breastmilk can be expected to nurse 10-12 times a day, which means an average of about 2 hours. I'd work on getting him to latch onto the breast (have you been working with an LC?) and in the mean time, try small, frequent feeds.

That is a lot for a three week old! My daughter had reflux though so I know what the constant spitting up feels like! I would burp her every two ounces but it didn't seem to really change anything. as long as he is gaining weight ok then you're fine and as long as it doesn't seem like he's in pain.

Spitting up is normal. Try making him take a break every one or two ounces. Feed one or two ounces and wait 60 sec. Feed one or two and wait 60 sec. Etc. he might not be registering that hes full until later because hes so hungry.

If that doesnt stop him then perhaps try some anti reflux meds from your doc. Its normal for babies to spit up that much that young. They are still getting used to digesting food. He could also need to be fed in a less reclining position.

After about 8 weeks most babies have gotten through their digestive issues. So if this continues after that then i would suggest seeing if you need to switch or supplement with formula. Some babies just cannot digest breastmilk properly.

He's doing this because he is NOT being burped thoroughly during and after every feeding.

ask your mom. and dad.
