I will be going back to work in about a month, when my son is 4 months old. I am wondering about the practicality of cup feeding as opposed to bottle-feeding while I'm away. It would be my mom who would do the cup feeding. We have tried bottle feeding with a BreastFlow bottle, and he just doesn't seem to like it. DH has given him his last feed before bedtime, and he wakes up hungry 2 hours later. So he's not getting enough and then loses interest, I guess? He will usually only get in about an ounce of the 3 ounce bottle, it seems. And it takes forever. Would he be better off with a cup? or that Medela SoftFeeder? Is this practical, considering I would be gone from him for about 6-8 hours, three days a week? Has anyone done it?
