One more thing I want to recommend you avoid: mommy blogs and Facebook groups. As first-time parents you will continue to look for advice and support, unfortunately many parenting groups are out there to serve as echo chambers for their anti-science, woo-pushing and child-endangering beliefs (chief among them, anti-vax). It's easy to get scared by and buy into this garbage when you have a new human life you are responsible for all of the sudden.
Trust your family and close friends' advice, trust your pediatrician.
