I SO hear you about the MIL disaproval about co-sleeping. My MIL and FIL keep saying (every time I see them or talk to them) that I must start sleep-training, in fact I've already left it far too long (DD is 7 weeks).
I just kept nodding my head and smiling (I'm a confrontation-avoider!) until I realized the other day that I actually AM sleep-training her -- just in my own way! My style is dramatically different from theirs (CIO for however long periods
) but I would say that my attachment style is much more effective.
You can explain or just know it in your heart that you're not co-sleeping *accidently* or because you're lazy or because you don't know any better. You're co-sleeping because it is a concious parenting choice.
In my case, my DD sleeps from 9pm through till 8am with one lovely nurse and cuddle in the middle of the night. It's glorious! She does wake up much more often of course, but she sees she's with me and we snuggle closer and she drifts off to dreamland again. I KNOW that if she was in a crib, I'd be up with her multiple tmes per night, exhausted and miserable for her too.
Interestingly, my MIL sleep-trained her other grandchild with CIO last year. This child now HATES her crib, fights naps and sleep and at 1 year of age, STILL wakes up during the night more often than my 7 week old DD.
So whose method is more effective?
I know it's hard; hang in there. Be proud!
