Dun worry..my mum said babies will be like that. and the hair may drop until 6mons if u don cut them all off... that's is the baby little hair. so she recommend me to cut it all off later whan the weathr is hotter so that baby's haor will be more strong and good.
On the other hand the situation that Mira said it won't happened in small baby. today i read back my case file (visual aids for my work). The blood disease (blood cancer) normally happened from two/three years old
Love the world, be joyful... Miracle will happen
