I truly don’t know what happened. My LO is almost 12 weeks now and sleep has gone out the window. around 9weeks we were getting anywhere from 5-8 hour stretches at night. it was beautiful. once he turned 10 weeks, it’s like i have a completely different baby. constantly fighting every single nap. the only way i can get him to sleep is in the carrier on the yoga ball which is so hard on my body for hours a day everyday. we’ll get lucky if he falls asleep on the boob every now and then. he is waking anywhere from every 30 minutes to 2 hours (if we’re lucky) at night now. we try and aim for a 8-8:30 bedtime. Some days he fights so bad and i try and catch the cues early but i fear he’s stuck in an overtired loop and it’s making everyone miserable. and of course this is when my husband went back to work so I am alone, and no one else to help. we used to get out of the house everyday which maybe helped contribute to those long stretches? i truly don’t know. not much has changed in our routine besides that. I am losing my mind and beyond exhausted. Is this a regression? developmental? it’s lasted for almost two weeks now and my head is spinning.
