My LOs are 6 weeks old and I was at the point of feeling recovered enough and stir crazy enough that when my former roommate invited DH and I to go out w/ her and a bunch of other ppl to celebrate her bday I really wanted to go. Plus MIL has been chomping at the bit to babysit ever since before these guys were born so we decided to let her and FIL put our little guys to bed while we went out. I explained our whole feeding and bedtime system, had everything set etc. and we were only gone two hours but when we got back both MIL and FIL were holding babies, looking shellshocked, claiming that they "would not sleep in the cribs" and "wouldn't stop screaming when put down". Of course this makes me feel terrible for leaving them and I'm nervous about them being way off their schedule, having been put down for the night a good two hours late....of course now they're sound asleep in their cribs no problem. I just wonder if I should have waited until they were older before having anyone besides me and DH put them to bed, or if that makes a difference at all. I dunno....how old were your LOs when you left them w/ a sitter? Am I just being an overanxious ftm?
Re: Too early for a sitter??
I'll have to have my parents and sister sitting the twins for an hour and a half when I go back to work at like 6ish weeks (if I get that long of a leave... we're still not sure)
I think they'll get used to the whole two babies thing... if it was their first night and they aren't used to twins, it was probably a little difficult
My mom watched our babies when they were only a couple weeks old a few times so we could run some quick errands. Don't sweat it. You also need time away. Hopefully, the nest time things go a bit smoother.
We are actually going away for a week now that they are just over 6 months old. My mom will be watching them again.
I don't think it's an issue of the babies being too young, more just the grandparents probably being a little overwhelmed as their first time w/ the babies. What we did w/ DS 1 was that for anyone who would be babysitting, and initially it was just family, we'd invite them over one evening beforehand for dinner while we're home, and have them go through the evening/bedtime routine with us, as well as just spend a little time w/ DS so that both the relative and DS would get used to each other and see DS's habits. We were all still figuring out what would soothe DS when he was tired or cranky. MIL and DH's aunt helped us with him initially - DS's aunt watched him for a full day when we had a wedding to attend when DS was 8 week's old, and since DH and I were both laid off after DS was born, MIL would often watch him for a couple hours so that we could go to career fairs and interviews. Of course one baby I'm sure is easier than juggling two. When the twins come, we'll probably do the same before anyone babysits and when possible have more than one family member watching them as a team since there will be 3 kids to deal with and that's a lot for us, nevermind anyone who doesn't do it every day.
Don't beat yourself up over it. You need a break every now and then too, your parents/in-laws will get the hang of things, and one evening here and there where the babies are off their routine is not going to harm your kids in the long run.
We had a postpartum doula 2 nights a week for the first month, so the first time we left them with someone else was when they were 6 days old. (We were at home, but sleeping.) But my brother and his girlfriend visited when they were 3 weeks old, with basically zero baby experience, and cared for them for 4 nights in a row, also while we slept. We went on a date and left them with my mom when they were 5 weeks old. So no, I do not think that 6 weeks old is too early - especially for grandparents! You NEED a mental break with newborn twins - it is effing hard work, and you have nothing to feel bad about. They will be just fine

Lost our first little peanut on 1/17/2012 at 9 weeks and 5 days. We miss you little blessing, but we know you were too perfect for this world.

I think around 4 weeks we left the girls with my mom for a couple of hours while we grabbed dinner. And then we never looked back, lol.
One thing we did that I think helped everyone was my mom and my MIL would come by during the day while we were home so we could nap. That let them get used to the babies and how we did things while we were there, so then if we would go grab dinner or run to the store we were all more comfortable with it. Don't feel guilty at all - just like getting used to twins was an adjustment for all of us it's the same for our families. They'll get used to it!
