Hello everyone and thank you for all of your support and advice. I have a question. My LO is 12 weeks old and is doing well, but I have noticed that he spits up A LOT when I breastfeed him. He doesn't spit up when given a bottle at daycare (I had to return to work part-time). Why is he spitting up with nursing? I thought that babies swallow less air while nursing than bottle feeding? Also, how do I know if I'm giving him enough milk in the bottles??? Will he act hungry if he wants more? We've been preparing 4 ounce bottles and giving extra frozen milk in case it's needed, but he is only taking 3 4-ounce bottles in 10 hours and is NOT nursing more than usual in the evening once we get home. I know there is alot of information here, but I just want him to get enough milk. (The past 2 days we've had several poops and 5-7 wet diapers per day). Thank you for any help that you can offer.
