Zoe is a gassy baby. And she hates having to burp! You know she needs to burp when she kicks and she flails her arms while doing a fussy cry.
She is solely breastfed. At night she receives a large 7 ounce bottle of breast milk and this keep her full until about 2-3am. It takes her almost 45 minutes to an hour to drink the whole bottle! I usually burp her every 10 minutes. Sometimes the burp really doesn't want to come out. That's when I stand up and walk her around, and she will eventually burp. If that doesn't work, my third resort is to lay her down for 5 minutes and burp her when I pick her up. I don't give her the bottle back until she burps. Sometimes I've waited as long as 10 minutes for a burp, but I know it's coming.
If she doesn't burp often during the bottle she is more likely to keep waking up to burp after the bottle is finished and she has been laid down for sleep. There have been nights where she woke up every 15 to 45 minutes after falling asleep, or just kept crying because she was so uncomfortable. Eventually the waking leads to her being hungry again if it persists for more than three hours. So to prevent all of these wake ups and her requiring another feeding in 3 hours, I try very hard to burp her during the bedtime bottle feeding. This leads her to sleep better and sleep all the way to 2 or 3am, her longest stretch of sleep.
She also tends to spit up a lot of this milk. I have found that burping her more often on the bottle helps to reduce, and in the last few days even eliminate, her spitting up. Some days her spit up got so bad that I needed to change the mattress pad, sheets, her clothes, and my clothes several times. Not to mention I have multiple spit-up stains on our wood floor from random spit ups I didn't even know happened as I was rocking her.
Elias was a gassy baby too. He had more trouble letting out farts and poop. When sleeping he would grunt and groan, kicking his legs until he was 2 months old. He did not spit up or burp nearly as much as Zoe does, so this is new territory for us.
