My girl is 16 wks now. If I swing a handkerchief infront of her, sometime she will use her hand to grap it n put into her mouth. She enjoy playing with her saliva or put her fingers into her mouth n lick. but her neck still not strong enough. have to support her head whenever I carry her leaning on my shoulder. your baby like to 'talk'?? Mine alway like to talk or mumble to herself esp. early in morning n will wake up everybody in the house.
