Have yoh tried a later nap in the late afternoon ? I know some people call this a danger nap but this worked for my little girl letting her nap from 4ish till 5pm then having tea and a play before bath and bed and she seams so go down okay at about 7/7:30 xx
I was reading somewhere that when they get “older” bath becomes an exciting play so maybe you can try and skip the bath and see how it goes? I never do the bath before bedtime because he loves it so much that taking him out is a tragedy - so I tend to do it during the morning/early afternoon
Could you maybe try and give me a little nap closer to bed time. Or move his last nap closer to the bed time so he isn’t becoming possibly over tired?
