Re: baby 10 months / production decrease normal?
How long are you at work each day? 15 oz would be about right for a 10 hour separation from your baby.
It's very common for moms to experience a decrease in pump amounts towards the end of the first year. The baby may be taking in more solids, leading to somewhat decreased nursing and consequently lowered supply. Or the pump may be giving out after months of heavy use. I wouldn't go out and buy a new Pump in Style- you just have 2 months to go and then you can start using cow's milk at daycare and contemplating pump weaning, if you so choose- but it might be time to rehab the pump. Get new tubing. Make sure the motor is in tip-top shape. Maybe try a different size of shields. A lot of moms find that their size changes as time goes on.
If new tubing and a rehabbed motor is enough to get you more milk, awesome. If not, I would just soldier on with that 4 the pumping session for another couple of months. I know it makes you tired!!! Just keep telling yourself that you only need to make it 2 more months.
