yes... you can apply. weather is changing fastly. some even apply ghee. But ghee will have a strange smell on skin with frequent usage. Coconut oil or olive oil is best.

actully my baby skin in dry cheeks and all so can i apply coconut oil over face too??

Apply coconut oil around her mouth so that saliva slips and won't stick to skin. It also helps in healing any rashes and keeping skin moisturising. As they don't have teeth and no control over swallowing saliva everytime, baby drools. It's very normal and no need to worry. Tie bib and keep wiping in soft muslin or cotton ( even dry tissue paper will do).
