What Nap/sleep training program have you successfully tried?

Alysha
My LO only takes 30-40 minute naps, a couple times a day and lately will only nap when I'm holding her. I try to put her down between 1-2 hours of wakefulness and she shows signs of tiredness but it's still a fight! She sleeps 11-12 hours at night but still wakes every 3-4 hours...This momma hasn't had more than 3 1/2 hours of consecutive sleep in over 5 months! 😳 HELP!
