Sorry if this has been done to death.
My daughter is 14 months old and, it appears, no where near walking. She can pull herself up, can stand unaided for about 5 seconds, and crawls very well, however she has no interest at all in taking any 'steps'. She doesn't cruise around the furniture, and if she pulls herself up on something just stays there and kind of bobs up and down. She'll walk a few steps aided but then loses all interest and sits down on her bum.
I'm not exactly worried, but I am finding it a bit weird that so many of my mum friends have walking babies but mine is not interested, and to be honest she's an absolutely lump and I'm sick of carrying her around!
