Hi. I would go for it. I did it when I had two girls, 2 and 3 years old. It was the best thing I ever did. I was so large (an "I" cup), and was able to have my nipples stay attached - meaning they measure you and sometimes they have to detach the nerves from your nibbles. The do detach your nipples and reattach them during the surgery, but some aren't so lucky to still have the nerve sensation.
I spent 2 nights in the hospital and ended up about a "C" cup. I probably missed a week of work. It just depends on you, but it's major surgery and between the anesthesia, the discomfort, etc., you don't walk in one day and walk back to work the next day. I think I had mine on a Wednesday, went home Friday, had the weekend to recover, and went back to work the following Thursday, and was ready to rest again over the next weekend.
With a 2 year old, and if you have a husband or friend who can be around, you can get around it. You just explain to the child that "Mommy can't pick you up." It was easier than I thought. You also can't lift your arms above your shoulders for a little bit, and will wear a bra that hooks in the front after surgery (you'll be bound in gauze for about a week).
I have to say the one thing - and maybe it's changed, but when you have breast reduction you will end up being "wider" in the breast. It's not noticeable, and since you are smaller you'll have more choices of bras. My sister had it done also and we have found Playtex Secrets, Victoria's Secret, and Lane Bryant are good fits. I found the lower the front underwire was in front, the better the fit for me.
It's the best thing I ever did. To wear a shirt that buttoned in front, to lay on my stomach, to not have people take a double look at my chest when they'd realize how big I was, etc.
I didn't have an issue with the belly at that time. Since then, I've had five abdominal surgeries for endometriosis and I tried to talk to them about liposuction due to fat, scar tissue and trying to build up the muscles down there, but no luck!
You will also notice a great relief on your back and other things you can do that you didn't realize you may have been limited in before. Go for it!!
