My DS is 17 days old tomorrow and used to eat 2.5-3oz every 4 hours until he hit about 10 days old then started wanting 3.5oz even 4 some feedings but now every 3 hours! Does it seem normal to be eating so much so soon and suddenly shift to an increase in amount along with shorter time in between feedings? Also, we switched from tommee tippee bottles to dr brown bc we noticed he was a little gassy and now we have solved that with the help of some drops but it's almost impossible to get him to burp! And since he was gassy once already, not burping as much now is nerve wracking. We split the feeding up and burp him halfway and 50% of the time he burps after the first have but only like 25% of the time will he burp at the end. I've tried diff burping positions. Any thoughts? I guess with the bottle switch and drops he could just not need to burp as much but I hear formula babies do need to burp more than BF babies so I dont know. He seems fine and is much better but I still worry he will slip again.

Re: 2 week old - FF how much? Burping?
Not all babies burp often so if he doesn't burp it's okay. My baby rarely burps and is content. If she doesn't burp within a couple minutes of rubbing and patting her back, and she isn't acting like she has air in her tummy, then I move on.
