Hello everyone, I am trying to lengthen my almost 4-month old's naps. He wakes up after 45 mins--- the end of a sleep cycle. On top of that, we are changing to a 4-hour routine. This seems to be going well, as he can last almost 4 hours b/w feeds. He sleeps great at night--- 11-12 hours with a dream feed around 11ish. He is a touchy, ultra alert baby who notices everything in his environment and seems to tire easily. When he wakes after 45 mins, I know he is still tired. So I go in, and calm him. He will calm most of the time while in the crib, but sometimes needs to be picked up. The best way to calm him is to use a paci, reassuring pattting, and a gentle voice. He will then fall asleep, and stay asleep when the paci falls out--- but then, sometimes, after 5-10 minutes he will squirm, wake himself back up--- and his eyes will pop open and he will be wide awake. I was concerned he had reflux, so he was on Zantac. But that made him very constipated, and so I stopped it. But now he is back to short naps. Today, I did pick up/put down with him using a paci and a calming voice and patting, and he had 2, 2 hour naps, but lots of help from me. It is just hard to do---- because I have a 2-year-old as well who needs my time and attention. I am not sure if the paci is a prop or what---- Anyone out there use a paci with pick up/put down? I have read both of Tracy's books over and over about pacis, and she seems to say it is okay if it doesn't become a prop. Thank-you to all of you fellow baby whisperers!!! This stuff does work! I used it with my 2-year old and he is a great sleeper and loves life!!!
