16 Weeks and want to get organised 🤞🏼

Hey mummas,

I am 16 weeks today and would really like to start buying little bits to store away! Not so much clothes (we’ve already started that!) more like nappies, wipes, other crucial things!

Can you all let me know what are must haves, also what size nappies do I need to buy for newborn? Without obviously knowing how big the baby will be? And also any advice on toiletry bits for myself would be very much appreciated 🥰
