newborn diapers

I used 2 packs of NB diapers together with the balance diapers from hospital before moving on to size S. My LO is averagely sized - 3.1kg upon delivery and Merries NB that i used could cater up to 5kg. Perhaps you can estimate based on all our sharing here, against your baby's projected weight from the gynae's review? Your qns is very valid; I had the same qns when I was in my last stretch!
