Is it a must to shave baby's hair?

DEAR mummy, I wanna say that G-ds creation is so amazing. babies are so wonderfully and fearfully created. I DID NOT shave any of my babies head until much later when I needed to. my no 2 is a girl and ppl keep telling me need to cut her hair until TODAY. Shes 18 mths and she has TOTALLY BEAUTIFUL hair. not gg to lie.. After she was born, her hair was funny looking and short. More on some parts. after a few months, NATURALLY, bb hair drops.. and new ones grow out. I ddint hv to do anything but nature took care of it. SO if you not wanna shave ur bb head its PERFECTLY fine. both my kids hv hair that PPL NOW look with envy. Not kidding..
