DD had been putting herself to sleep for about 2.5 months, but starting about three weeks ago she hit the 4 month sleep regression and has to be rocked to sleep or she has a crazy-baby melt down. While exchanging DD's crapped out humidifier/sound machine earlier today I saw the Homedics sound spa with projection and thought we might try that. I laid DD down tonight, turned the sound on (which wasn't new, she has always slept with white noise) and then turned on the little projection screen (It projects a rotating fish image on the ceiling). I left the room and went to watch her on the monitor. She laid in her bed and watched the projection for about 5 minutes then passed out. No fussing, no spitting the paci out, no screaming crazy-baby freak out! Momma is happy! I hope this wasn't a 'first time only' type thing and that it continues. Just wanted to share in case it might help anyone else.
