2 month vaccinations

Nylah • TTC #1 with my husband❤️ We are now pregnant!!!! I`m so incredibly happy!!!
FTM so I'm curious as to why some people spread out these vaccines? We will be vaccinating our children (so anti vaxers can keep it moving) in just not sure why/which ones to ask our pedi to give and which ones to spread out? Anyone with experience here would be a great help!
