Crossing feet at ankle!!

Hi Mommas...

My daughter is almost 10 month old... she is walking now... she rolled at 6.5 months... sitting unsupported since 5.5 months... pulled up to stand at 7.5 months, started crawling after she took her first step... she uses both her hands equally... can feed herself,.. my concern is crossing her feet at ankle... not while standing but when she is sleeping or breast feeding or playing... my friend mentioned it's a sign of CP, that got me freaked out big time... ialways thought that was a more comfy position for her... I always cross my ankles too... but still after what she said I can't help but freak out... any mom who knows anything about it....???

she smiles, laughes, babbles etc too...
