My DD6 has decided she doesn't want to kiss people anymore, fair enough I don't like close physical contact with people either 🤣 it took me a few days to not do it out of habit and she will give me one before bed occasionally as and when she decides, I don't ask. She is still affectionate with cuddling etc.
Her dad and a couple of other family members think it's odd and have used lighthearted bribery to try entice a kiss e.g I won't buy you things if you don't give me a kiss, her dad will say you don't love me if you won't kiss me. She doesn't seem to care what they say but surely this is a non issue and they should just respect what she wants.
I think they are being slightly childish and if she doesn't want to kiss anyone it's completely her choice and she is not being unreasonable is she?
