Not sure when you hug or kisses the child. When the child is busy playing, he/she doesn’t like to be disturb. Try to play with the child more often and incorporate hugs and kisses during play
are you the mummy or daddy? since when did it start? Do you have a helper at home? There must be some events that happened that triggered it...
Are u a daddy or mummy? Usually young kids resist affection from daddy especially if they are breastfeeding kids.
I think it’s quite normal. It’s part and parcel of child Developement
