hi .. my son has turned 2..now I have to take him for hep-a dose 2 vaccine and aslo typhoid vaccine.. cud u please help me out regarding how much the price would be.. and he is not going to poop on daily basis.. alternatively he goes.. is anything to worry a6. shall I consult doctor.. he avoids to drink water.. which makes me bother about his health.. another thing is dat he is playing alone.. he will not play with other kids.. he will go on roads running.. I'm as of now single mom.. he hasn't been seen his father yet due to some arguments we are leading separate life's.. so my son is growing with me and I'm feeling like he is undergoing autism spectrum disorder??
