My DS wakes up like clockwork at 40 mins. I have seen some other moms also saying there LO does as well. I read the NCSS and have been trying to get him to stay asleep while he switches sleep cycles. I tried shaking the bouncer (that usually just wakes him up for sure) or waiting for the second he stirs and rocking him, but he will sleep just not let me put him down. Is this something they grow out of? How did you get your LO to sleep through the 40 min timer?
