In one end and out the other
Miles always has the best farts while he’s breastfeeding, I had assumed it was because lying on his side was a good gas-escape position, or possibly because he just wanted to give me the pleasure of experiencing his farts while his butt is nearest my face, but last night I read that the sucking action stimulates intestinal contractions that push the gas through.
Babies are interesting. Farts are interesting. What’s not to love?
