I think ds2 is a snacker. He's 12 weeks and has really never nursed for more than 5 minutes at a time. I know I have a fast let down, I can pump a good 7 oz in less than 5 minutes (using double pump). He goes anywhere from 1-3.5 hours in between nursings and I nurse on demand. He seems satisfied with these short sessions, but obviously gets hungry again soon. He's growing well. I wouldn't really be that concerned except I'm going back to work soon and trying to come up with a routine for a nanny to follow with him and ds1 who is 2.5! Any suggestions for getting him to nurse longer?
