Feeling sad watching certain shows or films since having my baby.

Anyone else find they are more emotional when watching films or tv shows about kids and families? Since having my baby I’ve found I get upset more if a show has something sad about a family. I’ve just had a little cry watching a muppets Christmas carol when it spoke about tiny Tim dying. Is it weird that it upsets me to think about losing my family? Or my family breaking up? I find myself not being able to watch certain films as I know what happens if it’s about these things.
