Please someone confirm or deny something for me?

Someone has told me that letting a baby (she's 14 weeks old) stand up for too long can damage their hips. Is this true? I'd have thought that if she wants to stand up I should allow her as it will strengthen her legs for walking etc when she's older.

Also as an extra - is there things she should be doing development wise by now or is she too young to worry about that?

Cheers all

DD1 was like your dd.

She never crawled but was walking unaided at nine months.

I have to say at 4.3yrs is the only thing wrong with her legs is that they are so bl**dy long (they go all the way to her armpits . I have to get 5-6yrs trousers for her then take them at the waist as she is very skinny. Of course i'm not jealous as i am verticaly challanged 5ft.
