My daughter is 18 months next week. She can't crawl yet, doesn't even try.. has never pulled herself up at anything, doesn't even try that. She walks but holding our hand. If we try let go she just falls. And it's usually falling forward with a massive bang onto her face. She doesn't like cruising. I've also realised then when she's holding our hand stood up, if she wants to pick something up, she will not bend her knees at all, just bends at the hip and hangs off her arm.. thinking about it the only time she bends her knees is when she's just sat on sofa or highchair etc. Hmm I don't know, do I give it more time?
