DD2 is almost 5 months and has been spitting up more and more. she always needed to be burped and would take a while to settle in the MOTN, but now falls right back asleep and can burp herself, but those burps are filled with either straight milk or curdled milk. a lot of the time it's right after a feed, but she also does it an hour after or even after a nap before she's nursed again. DD1 almost never needed to even be burped, so this is brand new to me!

is it something i need to look into more (reflux? allergies?) (she's gaining eight and sleeps like an average 5 month old, is way happy) or just have to make sure i have burp cloths on me at all times and just be resigned to soaking all my clothes and hers in oxiclean?
