questions about CIO

i was talkign to my dh's aunt and she was saying to try cio. My ds is 4 months is that too young?
I was telling her how you go in every 5 minutes then 7 mionutes then 10 minutes tecand she said she just let them cry( no me than 20 minute) she said to go in is like teasing them. Do you agree?

My ped said we could do it at 5 months to wean DS from taking bottles at night. We did, then he got sick and the whole thing went to crap til he was a year old

As for going in, we can't go in with our DS, makes it worse, but for some kids that works

Re: questions about CIO

We started CIO pretty early and did it in stages. The first few nights I could only let her cry for maybe 1 minute before I had to go rushing in. For us, she started sleeping 8 or 9 hour stretches at 3 months and consistently 12 hour stretches at 5 months. I think it had a lot to do with what she was eating - starting purees at 3 months, etc.

Around 4 months I'd say I was letting her cry for maybe 10-15 minutes before I'd check on her.

Re: questions about CIO

Personally, I could never CIO a baby at 4 months. I think it's way too young. I couldn't stand to hear my ds cry knowing that all he needs is a little TLC from me or daddy to make him feel better. My understanding is that sleeping through the night is a developmental milestone and has little to do at this age with learning how to soothe themselves.
