My daughter is 5.5 months old. She was EBF, though we just started introducing solids, and she naps pretty well throughout the day- about three times a day, one hour or so/nap. We bed share, though we tried cosleeping which worked for about a week and then her sleeping started going downhill and has been in a progressive decline since, now were back to bed sharing.. She used to sleep 10 hours a night, sleeping through 7 hours straight- feed and then back to sleep for another three hours. Now she's not sleeping- I'm talking half hour spurts of restless sleep throughout the night in which she's rooting the whole time, until about 2AM. At that point she's up until 5AM, fussing and squirming the whole time. Could it be teething? A crazy random growth spurt? It's 415AM as I write with my right hand and rock her with my left, while sipping on a glass of wine to keep me from certain tears. I feel so alone as husband doesn't want to "deal with her sleep issues" and I am just- exhausted. Is this behavior common or could there be a physical change happening with her that I'm just not seeing? Can anyone shed some light on this issue?
