FTM, trying not to worry too much...

How old is your LO and how many poop diapers and pee diapers do they have per day? Also, how long do they eat for each session? My son is 11 days old, and usually eats 7-10 minutes every 2 hours. People keep telling me to make him eat longer, but he has 8-9 poops and pees per day, that's a good indication that he's eating enough right? I'm a FTM and trying not to let people freak me out. Thanks in advance!!
