Query: Great product (but not recommended by therapists)

Our 8-month old twin boys absolutely love this walker! They've used it constantly since we bought one for them to try out. They love being able to get around themselves without needing adult assistance. They chase the dogs and us around the kitchen, family room, anywhere they can get the walker to go! Unfortunately, our twins' pediatric occupational therapist says we should limit their use of this type of walker. Apparently the way the seat positions them, it promotes toe-walking and makes it more difficult for babies to learn to walk properly. This was confirmed by a friend who's 1-yr old nephew used this since he was 6-months old and now walks on his toes all the time. We'll continue using it since the boys enjoy it so much, but we will be limiting the amount of time they stay in it.
