Question - 2 week old formula feeding

Cristin

My son is 2 weeks today - we are formula feeding. He only has about 1-2 ounces a session (usually every 2-3 hours), but it can also take him an hour to finish the bottle, or 40 min for 1 ounce. He often falls asleep feeding and I’ve tried all the tricks to get him to wake and finish quicker (tickling feet, moving positions, changing diaper part way through). This could be totally normal for his age and I’m just getting ahead of myself, but wondering if other moms found the same at his age?
