@Kelsey Ahh, it's been a shock as he's been doing so well with bedtime the last 6 months. I guess we just have to wait it out!
It's horrible isn't it, just when you feel like you've nailed it boom they shock you! Sending lots of positive vibes, try and keep all your usual routines consistent Google tells me too!
My little girl has been taking along time to go to sleep at bed for a good month or so. Last few days she's also started refusing naps, Google tells me 2 is a perfect regression age!
