Anong signs ng pagiging "sakang" sa babies. . Pano maiiwasan to... and pano po magagamot? Got a 9 month old twins

My mom used to massage our legs everyday when we were babies para maging proportion ung shape and distance ng legs. Sobrang tyaga nya in massaging our legs that's why we're thankful to her walang sakang samin. she also did it to my eldest child, and he too has really nice shape ng legs. I failed to let her do it with my youngest though kasi we already live far from her. Sadly, medyo sakang sya. Napapagalitan nga ako kasi hindi daw ako marunong mgmassage. :(
