Girls, it's like our baby is screaming! It's been 2.5 months, but we can't sleep well at night, waking up somewhere between 13:00 and 14:00. We then sleep for 30 minutes every hour and a half. So in a day, that's about seven times. It's hard to fall asleep at night, on our arms, rocking, and only falls asleep around 4-5 AM. Sometimes at night she cries, gets fussy, and colic seems to be bothering her still. I tried waking her up before, unsuccessfully. Can you help? Maybe there are some tips, I'm just running out of strength.
