I just want to know if I'm being unreasonable here and if I have a reason to be upset. I went to the zoo today with my parents, other half, sister, her other half and their three year old son and my five month old daughter. My nephew loves his cousin but likes to try and kiss her which I don't like. Today he went to kiss her on the lips whilst my mum was holding her so I put my hand on his shoulder to prevent him getting closer (he always has a cough and a runny nose) and I told him to kiss her on her hair instead (where I wipe straight afterwards) so my nephews dad then mumbled 'he's just a kid no need to push him' which he didn't say to my face but so I could hear. My nephew wasn't upset but this upset me because I feel I have every right to protect my baby and I did not push him away I simply put my hand on him to stop him touching her lips. My sister also asked why he's not allowed to kiss her on the lips. I was having a lovely day but it kind of ruined it for me :(
