Re: Weaning at 10 months
It doesn't sound to me like you child is weaning- just cutting back. He may pick up his nursing frequency again, when he's teething or going through some other developmental milestone. If you offer the breast more frequently, will he take it?
As a PP suggested, if nursing on nights and weekends is going okay, there's probably no reason why you have to pump. Although you may want to continue anyway, for 3 reasons: first, you'll have that much more milk in your freezer stash, second, there are health benefits to producing milk (decreased risk of breast cancer, diabetes, obesity) that increase the longer you go, and third, a few pumping sessions may increase your milk supply for the times when you are together with your baby and he wants to nurse.
Are the sitters who are with your child in the mornings offering the bottle before the solids, or after? Sometimes a kid will fill up on solids instead of mama's milk, so waiting until he finishes the bottle (or breast) to offer the solids may increase his breastmilk intake.
Another way to get your milk into your baby is to mix it with his solids: breastmilk can be used (for example) to make cereal or to thin out some applesauce or sweet potato mash.
Finally, you probably don't need to give your baby a bottle before bed. I know you said that you like to see him take 5 oz before bed and you only pump 4, but judging your milk output when nursing by what you pump isn't always a good idea. Most babies are much more efficient at emptying the breast than a pump is.
