I wrote a blog:
Increasing Your Milk Supply Through Galactagogues It has all those things like prescriptions, fenugreek, mother's milk. However, I just want to make a few comments about your op if you don't mind:
First of all, babies will nurse every hour or so on occassion. This is their way of building up your supply. They are hitting a growth spurt, or are about to. Their nursing like that IS NOT AN INDICATION OF DWINDLING SUPPLY.
Secondly, you mentioned that dh was giving an occassional bottle? That will mess with your supply and if you want to keep nursing you need to stop giving bottles period--at least for now. You'll be able to get that break in when your babe is a little older.
Thirdly, you should not be pumping right now. It is the antithesis of helpful. The best and most effective way to build your supply is to let your baby nurse as much as he wants. Pumping (unless of course you have to) during the first 6 weeks post partum often has the result of decreasing your supply, it makes it harder on you and harder on the baby.
Finally--the only way you can truly tell that your supply has decreased is IF YOU ARE NOT CHANGING ENOUGH DIAPERS and/or baby is not gaining weight. Pumping is not a good way to tell if supply decreased--especially at this stage. You should have at least one poo a day, and 6-8 wet diapers a day. (Probably more like

. Also, your baby should gain about 1/2 oz to an 1 oz a day.
So my honest advice in this situation is just nurse your baby. Carry him, love on him, make sure you're drinking and eating enough, and nurse him on demand whenever he wants. I'm sure you're fine. If for some reason it's still not working out, a galactagogue will generally work within 24 hours. But again, before doing any of that--just keep nursing!
