We've been at it for nine months. The support is good standing up, but if you hold her under the armpits, she immediately bends her legs or tries to sit and crawl away right away. One doctor says this isn't normal and should be a support, another says it's perfectly fine. She stands next to the support with all of her feet, but when she tries to walk, she does so on tiptoes or flatfooted. But we don't rush to walk, she only tries to move along the support or the cupboard if something interesting catches her eye.
