@pz128 OP I’m in the exact same boat at 12 months. If my baby sleeps in the crib, the max she’ll do is 1.5 hours for the first stretch of the night, then it’s waking every 15-60 minutes looking to nurse. We started bed sharing at 6 months for survival. Lately (months 11-12) sleep has been really bad even in our bed, with constant overnight nursing that has me in a deep depression from a year of interrupted sleep. However, we did have some longer stretches from months 7-10, like some nights she’d do two 3 hour stretches, or a 4-5 hour stretch at the start of the night followed by the hourly wakeups.
What I am doing now to address this, as it’s not sustainable, is the following: slow crib acclimation + slow night weaning.
We start the first sleep cycle of the night nursed to sleep in the crib. When she wakes the first time, if I have energy, I repeat nursing in the crib and get her back to sleep in the crib.
Second wake up we bed share for the rest of the night, and I’m doing the Jay Gordon night weaning method (Google it) for bed sharing families. We haven’t progressed past the initial 3 day approach, because my baby is a really tough case and with this method unfortunately you have to lose sleep to get sleep. But I’m hoping after this week we can move to the second 3 day stage.
