Just curious- how old is your baby and how long do they nurse?

I stopped breastfeeding DS for medical reasons at 3 months and I was pumping most of the time before that so nursing anything above an infant is new to me.

DD is 5 months old and she usually nurses for less than 10 minutes...usually between 5 and 8 I'd say? I offer both sides. She'll pull off because she'll get distracted by something but she'll usually latch back on if I offer. Sometimes after eating she'll spit up quite a bit (not in distress or anything...just along with a burp) so I'm not sure if I'm trying to make her eat too much? But I figured as long as she'll take it...idk!
