Re: 10 month old, waking at night
research has shown that breastfeeding moms (and dad) get more sleep. like 45 mins a night, says the Breastfeeding Answers Made Simple reference book. it's SO much easier to just nurse the baby and fall back asleep - it settles the baby faster, you don't have to fully wake up and mix a bottle, etc. it says, even when dad gives the bottle in the middle of the night, that leads to less sleep for mom (on average). so by all means find the routine in your family that gives you the most sleep, but be creative about how that happens: consider co-sleeping or bed-sharing, going to bed at 7 or 8 pm when baby does, etc. that is what allowed me to cope when i was working full time witha little baby.
