Okay, so I guess my 4mo is going through that regression crap because he used to go about 5 or 6 hours without waking up. Now, we feed him around 7 or 7:30 (even giving him rice cereal!) and then he wakes up at about 2-3 more times after that between 8pm and 5 am. It’s horrible. We moved him to his room but he’s still swaddled from waist down in his rock n play. Any moms have successful sleep training tips? How long can you let them cry. My husband and I are desperate! Help! I just want him to sleep in his crib and sleep through the night
