Congratulations to all of the new mothers!
Regarding sleep - with or without the baby. Here's what we did.
The baby slept close, but not in our bed. When the baby woke, I would nudge my husband, he'd go and get the baby and bring it back to me to feed. He'd go back to sleep.
While feeding the baby, I'd mostly sleep too.
When the baby was finished, I'd nudge my husband again and he'd take the baby back. Usually I'd be asleep again before he was back in bed.
Unless the baby was particularly unsettled, the baby got fed and neither my husband nor I missed out on too much sleep.
