The book on breastfeeding wrote no need to burp but I realised I still need to burp my baby, perhaps because he couldn't latch very well yet and suck in air.
Spitting milk is normal if he's healthy and he didn't spit out too much. My baby spit all over, dirty our clothes, his clothes, his bed, our bed and even on the shopping mall carpet when we brought him out... and its frustrating but it goes away when he's about 4 months old, when he's stomach is more mature to retain the milk in his tummy and not spit out. My mom said spitting is good as it means baby has had more than enough milk to drink. haha.
