Is having a newborn in the winter any harder?

My daughter was born in early October when it was still warm and we could easily leave the house without worrying about germs and sickness. Is it different with winter newborns? Like would I have to be stuck in the house all week to prevent anything. (Not saying it’s bad. I would put my baby first of course) just trying to plan baby #2/figure out when I want to start TTC. Weighing out pros and cons of winter newborn vs spring newborn. Any input is appreciated 💗
