OP baby walkers aren't great for babies for lots of reasons. Both my DS's were very active from a very early age. DS2's default position from a few months old was standing on your lap. He got very very grumpy when he got put down, so I almost got him a Jumperoo just to get some peace
. But I decided against it as I firmly believe that little babies need to be on floor so they can start to move themselves around by rolling, crawling, bumshuffling whatever, then start to pull themselves up when they are ready.
Floor work is really important for muscle development, and unfortunately baby walkers don't allow them to move and develop their muscles as nature intended. I know loads of people say that their child used one and they were fine, but your baby will be better off on the floor, honestly. The other issue with baby walkers (and one of the reasons the Charted Soc of Physios wants them banned) is that they cause a lot ol accidents. As children learn to stand and move around, they also start to develop an awareness of their surroundings and how to negotiate them safely. A walker puts a baby a walking height and gives it the means to zoom around before it will have started to develop those skills (I know when a baby starts to walk accidents are par for the course, my babies are testament to that, but walkers are much riskier!).
Sorry, as you can see I'm pretty anti-baby walker! (I'm an OT so my background has a lot to do with it).
DS2 was crawling before 6m, he's now 7m and has been pulling himself up for ages and is just starting to cruise. They all go at their own pace, but I can tell you from experience with DS1 that having an early walker can be a bit of a nightmare!!!
