When I did this with Josie, way back when, I did it for maybe a week, and then one day I took a nap and didn't wake up at the 45-minute-mark - and neither did she!
Took maye 7-10 days for her to get used to sleeping thru that 45-minute point.
I can't find the post either now that I'm looking, which bites 'cause it took me AGES to write it all out, but maybe someone else'll find it. (It's LATE here and I have no business being awake at this hour! LOL)
Oh, yeah, the 20-minute thing: It's not unusual for babis to sort of "jerk" at about the 20-minute mark as they drit off and work their way to deeper sleep. Some moms find it'shelpfulto hold theirbabies or stay with them till that point has passed till the babies get used to sleeping thru it, some swaddle snugly so it's less of an issue, and sme babies wake up regardless for a while. I found that using a small receiving blanket folder lengthwide in 4ths and laid across baby's tummy (worked with both girls
while I laid my hand on them and then SLOWLY withdrew it seemed to give them the feeling of weight on their tummies that they liked and seemed to help me leave the room earlier at naptime.
HTH, but if it doesn't help, please feel free to post back. Our modem is acting up but I hope to be on again soonish!
ETA: Yeah, I'm still on. It was bugging me about the post I wrote way back but it's on FAQ's. Try .
