to consider sending DD off with DH so I can sleep?

[bagelmonkey]

DD is almost 1. She has never slept through & usually wakes 2-3 times a night. (She's been ill this week, so things have been a bit worse.) I do all the night wakings because I've been BFing & it's the quickest way to get her back to sleep - I'm too tired to do anything else. DH doesn't hear her if she wakes up. I can't sleep if she's awake & even if DH does go in, I can't sleep until she's resettled.
She's still BFing & hasn't taken any other milk yet, but will drink water or juice from a sippy cup.
DH is taking a week off work next month & wants us to go to visit his parents.
WIBU to send DH & DD ahead so I can hibernate for a few days before I join them? Or to ask to stay at SIL's house & leave DH & DD with PIL so I can get a few proper nights sleep?

Not unreasonable in the slightest. But I feel your lack of sleep pain!

DH and IL will probably think you are but no you're not.

I once slept on the settee and left (now ex)P upstairs dealing with DS. It went down like a lead balloon with him and IL. it was 10 years ago so I was back at work fair enough only part time but I still needed my sleep too.

YANBU - but I am in the same position with one-year-old DS and have no idea how to sort it so that he'll get through the night without me being there. DH would be up for letting me hibernate, but DS won't take a bottle and faffing with a sippy cup (which he'd only take about an ounce from at best) would only wake him up, not resettle him. So if you crack it, please let me know how!

YABU if you're still BFing her. If you want to night-wean her and then get your DH to do the overnight duties in your stead, that's one thing, but to send them off for several days without you is unreasonable. I understand the position you're in as I have an 8-month-old who's still BFing at night and in the throes of teething and I would give a lot right now for a decent night's sleep. But I wouldn't just send him away.
