So my fiancé wants to go down to California for thanksgiving or before thanksgiving my son will be a month and a few days old. My fiancés sister in law is telling me not to go because my son is to small and that I shouldn't expose him on getting sick and that I should wait until he gets his 2 month shots😔 The only reason why I wanna go is so my family can meet my son because if I don't go they won't meet him until next year till April or May he's already gonna be bigger and I want my family to meet him now and not later. What do u mommies think I should do go or stay?
