1. Diapers (i used almost 4 big packets in the 1st month) 2. Wet wipes (not necessary because you can use a cloth and warm water to clean) 3. Swaddle (they need to be swaddle at least for the first 3 months) 4. Newborn clothes (they don't need that many because they will grow out of it very fast) 5. Mitten/booties (only the first 2 months) 6. Bath essential (shampoo, soap) 7. Nappy cream 8. Body lotion 9. Burping cloth 10. Pacifier (personal preference) I recommend you to prepare all these at least when you enter third trimester of your pregnancy.
