What causes this? My baby is 6.5m. I'm a STM and my first never did this! During the night, at least once, baby will wake up and not settle for 1.5hrs. Why is this? It's been happening for at least 2 months now! My eldest used to have a feed and not really wake properly, immediately back to sleep. This one just wants to party all night.
3 consistent naps a day totalling 2-2.5hrs and that fall within the wake windows. Regular wake up time of 7am and bedtime of 630/7pm. Bedtime routine consistent. Breastfed. No health concerns. Still happens even if given calpol (e.g. when teething). White noise makes baby stop still in their awakey party but doesn't help them actually go to, fall or stay asleep.
Any thoughts?
