Don't tell anyone here I have some Alva's... Lol
That being said I really liked my nb Alva'a. They fit a long time and are really trim. Only issue for me was the laundry tabs. But for the price you can't complain too much. I found some of the old sized BG and they fit about the same. I know this is completely irrational but I like to put them on her when I know she is about to poop. I know that all diapers are for poop... I just can't convince myself to put one of her prettys on her for the horrific morning poop.
We are at almost 4 months and they still fit with plenty of room.
