Big baby- what size clothes and diaps??

Bradi • Mama to two precious boys (ages 2 and 4) 💙 and just found out we are expecting our third! 🥰

So they keep telling my that my baby is measuring 2 weeks ahead and is a big baby. Does that mean i need to pack some bigger clothes than newborn or will he fit into those? Also, diapers, will i need to bring some size 1 or will he fit in newborn? Am i totally overthinking this?

Y’all help me I’m a FTM! 😂😂
