My DS is 9 +1 months and I went back to work full-time 6 weeks ago. I pump 2-3x at work and usually take home anywhere from 10-13 ounces for him for the next day while I'm away. Typically he will drink that; sometimes he will need a bit more from my freezer stash, or sometimes there is an ounce or two leftover. When I am home, he typically nurses every 1.5-2 hours during the day; he will usually wake 2x a night to nurse (and more often in the hour before he wakes up for the day). We cosleep.
I've noticed my supply is dipping. Just now, it had been 3 hours since I'd nursed him this morning, and I was only able to produce between 4-5 ounces from both sides (usually I could easily get 6, total, if not more, from my first pumping session). I did spend some time away from my son this weekend which I'm sure didn't help, but I've noticed the pumping sessions being less "fruitful" over the past 2 weeks.
He has never had anything to drink other than breastmilk and sips of water, and I am determined to continue to give him only breastmilk until he is 1 (don't want to supplement with formula for many reasons). In my ideal world, I'd be happy BFing him until he is 2 years old, and although he eats solids, he is still quite a nurser. So I'm not anticipating weaning any time soon and am following his lead.
My concern is that I don't know how many more months I will be able to pump enough for him to have during the workday w/o wanting more. My freezer stash is almost gone already (maybe 20 oz left?). I'm curious to know your thoughts on adding in goat's or cow's milk in addition to breastmilk bottles after my son turns 1. I want him to have breastmilk as long as he's willing and I can provide it, but I don't want to go crazy trying to squeeze out every extra ounce here and there; I already have a lot going on from day to day and don't want the added stress on myself, especially since he is an older baby.
Any recommendations on what I could do? I'm hesitant to start him on cow's milk in a few months but want to be sure he is getting enough milk either way. I just want to have a plan in mind in case my supply keeps dwindling. I'm hoping I can make it 2.5 more months pumping about 10 oz. for the workday.
