I treid Boots own nappies & i really didn't like them. Everytime i put one on he seemed to leak everywhere & the bit that fasten doesn't really stretch like pampers or huggies.
I actually use Asda own brand (not smartprice, little angels) & they are fantastic & are cheaper than boots as well. they have the strectchy fasten bit as well.
for newborn size 1, £1.64 for 24 napies & newborn size 2, £3.98 for 46 nappies.
