Hi all. We have a 4 month old and an 8 year old. Our little one was always a good sleeper but we're struggling with the 4 month regression and want to get our nights back. I'm wondering how people do a bedtime routine when you have to stay in the room with the sleeping baby, but also have an older sibling that goes to sleep at 9pm. Most routines I see online are the baby going to bed at 6 or 7pm and that just won't work for us as our older daughter is normally starting evening clubs at that time, so we can't be stuck in the bedroom with the baby.
Any tips are massively appreciated.
