Walker and Jumparoo

Abigail

So my mother bought a stationary jumparoo for LO for Christmas and my MIL just said she wanted to get him a walker. I told her my mom bought he jumparoo already and she said she could get the walker. I’m wondering if I should tell her to get him something different. They seem like the same thing just the walker is not stationary?🤷🏻‍♀️ FTM looking for advice on this!
