I can tell you that I tried this with my daughter and with my Medela Pump-in-Style did not have good results... or I guess I should say the results were no better than pumping as usual. However, I did notice that when I used my Avent handheld, I could often better encourage let-down and could get more milk more frequently this way. It was also better for me when I was painfully engorged.
If pumping exclusively is working for you, then I say great! I never minded pumping too much, but I would have much rather nursed any day- I found it relaxing and more comfortable than the pump and I enjoyed seeing my baby look up at me and pat my breast, etc. It was very much a bonding experience. If you have pain while nursing or your baby has issues with nipple confusion, etc. it would probably be WELL worth it to see a lactation consultant. However, if you're content, then happy mommies make for happy babies! :)
Also, for supply- things that really worked for me (I worked 60+ hrs a week away from baby, so I did a lot of pumping too!)
-Eating oatmeal always increased my supply
-Making sure I was hydrated. By the time you are thirsty, you are already dehydrating. Take water bottles with you everywhere you go!
-Looking at/holding my baby while nursing, or looking at a photo of her and smelling something she wore or a blanky of hers while I pumped.
-This may not be an option for you, but I also liked the times when I could pump one side while she nursed the other- I found I had a much stronger let-down and pumped more during those sessions. It can be a juggling act though, depending on how your pump is set-up.
Congrats on your baby and your decision to give your baby the best food on earth! :)
