Well if you've never tried it, you'll never know. I thought it was going to be uncomfortable, and it definitely wasn't, it's hard to just strictly pump from beginning until you want to stop, breastfeeding is an amazing bonding experience, if you think you may be able to give it a shot, even once, I recommend doing it, but if not, pumping is the next best thing for your baby, remember not all women lose weight from breastfeeding, so don't make that your sole reason.
I think it's weird and it's going to be uncomfortable
You can pump, that way you're getting breast milk, he's getting the nutrients he needs, and you may lose weight that way, is there a reason you don't want him to latch on?
