Re: HElP!!!!! - My son will not nurse (3 months)
I don't think you need to look for a deeper reason for his difficulty with nursing than the fact that he's 3 months old and he has never gotten much practice at it or much reward from it when he has done it. Babies can be quite picky about how they are fed, and they're smart, too. Your baby is offered the breast and he's probably thinking "Oh, this again. Don't know why mom is so insistent about it. It's so frustrating for me, and I am HUNGRY! Well, I'll do a token suck and see if she'll give in and feed me a bottle afterwards."
If you decide that you have had it with trying to get your baby to nurse, that is okay. No-one can say for sure whether or not your baby will ever go back to the breast, and considering the effort involved in trying to get him there... Only you know if the cost is worth the potential payoff.
What sort of pump are you using? You're exclusively pumping and IMO that means you should be using either a hospital-grade rental or a really excellent double electric pump (e.g. Medela Pump In Style, Hygeia Enjoye) with correctly sized shields. If your pump has failed on you once, and pumping is taking forever, it might be a good idea to trade up for a better machine and experiment with different sizes of shields. Increasing your number of pumping sessions is also a good way to get more milk, but I know that 'a not always possible or preferable- as you said, it keeps you from your baby!
One thing to remember, when it comes to pumping, is that it doesn't have to be all or nothing. Pump what you can, and if you start falling short, well, that's what formula or donated milk is for. Any amount you can provide is good for your health and for your baby's.
