Taking Cara Babies

Alright I caved and bought the 3 & 4 month guide from Taking Cara Babies and will be starting it tonight. My LOs naps are an issue and her lack of ability to put herself to sleep is the biggest issue we're facing. Nighttime sleep isn't too bad as she usually goes about 5 hours then feeds and goes back down for another 3 or 4 hrs. Used it for her naps today and while she still woke up at the 30 minute mark I was able to elongate her first nap of the day at least. I'm nervous and want to hear from other moms who have been using it to help their babies learn to fall asleep on their own. How long until you saw noticeable results? I know it says it takes about 2 weeks to 28 days to really be effective. Just want to get some first hand experiences from you all.

TIA 😊
