OKay, my first attempt at cry it out has gone okay. I put my 6 month baby boy down for his nap and this time did not use dummy...even though he cried. Thankfully, he cried only 3 mins and was sleeping by 5 mins for his nap. Now, tonight I will continue and not use the dummy even if he wakes at night. To be sure he is not hungry, I will wake him at 10:30pm and give him a milk feed (although he usually only drinks 2 oz anyways at this feed!). I am not looking forward to letting him cry. But hopefully, it will not be for too long, since he is pretty good at falling asleep during the day for his naps. Its just at night I usually dont let him cry bc I worry he might wake my 2 year old up!
