What will you do if your family members use paper to pat on your lo's head?

I wouldnt do anything, i guess its very much to each its own. Some may not be bothered by it, some may not like it. If it bothers you perhaps you should tell them nicely not to do it. Or ask yourself why are you upset, if baby is happy or does not seem bothered im usually okay. Unless baby seems disturbed or irritated by it. Then again, dont feel bad dear, everyone is different.
