Hi A.,
No judgements on stopping breastfeeding, but it sounds like you're stopping because you're milk production is low, not because you want to.
If you want to boost your milk, all you need to do is start taking 3 tablespoons of flax oil a day. Trader Joes sells it as does whole foods and most health food stores. Have it in a protein shake for breakfast. Nice extra benefit, it burns fat!
I went back on the pill within 4-6 months of having my two kids, but breast fed til they were both 2 years old. Never had supply problems because of the flax oil. It's an omega 3, so it will also help your babies brain development.I told a friend about the flax oil and she had to stop because her milk production was too much!
My kids are now 6 and 9 and I'm still taking 3 tablespoons a day, easy way to burn the fat. Go figure.
When you do decide to wean, I don't have any tricks for making formula taste better, but you might try putting band aides over your nipples. My kids had the hardest time giving up the breast that I finally resorted to that and it worked.
Good luck to you what ever you decide to do!
