I only did until she was two months and I had the mirror thing si I can keep and eye on her I had to drive everywhere alone while hubby was at work as long as they aren't eating they are fine

My baby is 7 months & I still do 😊

I go in the back with my baby if my man is driving but if I'm driving he sits in the passenger seat and she'll be 1 next week. she'll only sit in the back by herself if she has snacks
