Baby ok in walker since I don’t have a jumper?

Kimberly • Mommy to a little princess ❤️

My mom bought us a walker for Christmas, we don’t have a jumper or anything like that for our almost 6 month old would it be okay to put baby in walker or will it affect her legs? My mother in law insists it’s going to cause leg deformities because she will try and pull herself? I’m a first time mom so I have no clue can you mommies please help me out? And let me know if it’s okay to put her in or not?
