My LO previously slept from 6.30pm - 2.00am, wake up for a feed and then go back down from 2.30-6.30am. They're 4.5 months.
For the past week and a half they've started waking up screaming every hour until the feed and then every 20-30 minutes from going back down. It takes between 1 and 15 minutes of calming them down and back to sleep.
At bedtime they're put down awake, patted and the light turned off so not fed or rocked totally to sleep.
Is this the 4m regression? Is there ANYTHING I can do to get them back on track? I'm going out of my mind...
