Only latching for 10 mins

Jill • 💙2•17•19💙

I just had my son on Sunday morning so he's almost 3 days old. When I can get him to patch properly he's only eating for 10 mins then falls asleep or is uninterested. Is he eating enough? This just started when we got home this afternoon. Up until now he's been latching for 20-35 mins. I'm a first time mom and I just want him to be full and I'm really discouraged that he's not staying latched....
