We use a bath mat too and use a shower head over the bath because he refuses to sit or play 😅
I agree with the other comments. I use a bath mat as well for my daughters.
My little boy did this it became unsafe. We just laid him in the bath with a bath mat and filled the bath up to halfway of him. No he sits in the bath and plays, he loves it. I say scrap the chair.
Straight into the bath, we got a bath mat. Have been doing so since 9 months
Agree, bath mat!
We use one of the grippy bath mats to stop him sliding when he stands up, and that works well.
