I think (and these times are not exact, because i can't remember exactly) that around four weeks the baby would eat more consistently every two hours, and became much more efficient - so he ate more like 20 minutes rather than an hour or so.
Stick with it mama, you'll be so happy you did.
my little guy is 8mos old and i look forward to our snuggle time now. It's a great way to connect/reconnect with your baby. I find the reconnection extremely important to both of us as a full time working mama. We both just breathe a big sigh of relief that first nursing after a long day apart.
BUT at the beginning, the sigh of relief would often come from me when I could put him down for five minutes and take a shower. I remember reading in one god-awful baby book (i think it was the baby whisperer - she and i just did NOT connect ) "if it's three in the afternoon and you're still in your pjs, something is not right." I wanted to kick her. I remember going full 24 hours without getting out of pjs. And i wish i'd never read that book, because instead of enjoying the moment, i kept thinking, "i shoudl take a shower. i should get stuff done." Try try try and be in the moment. It goes so quickly
