It really depends so much on the shape and size of your baby, childcare, drying facilities, do you expect to have other children etc.
I have the following in my stash:
Bumgenius Elemental Joy pockets stuffed with Little Lambs Size 3 bamboo inserts. These are bombproof for us, really absorbent and slim fitting and never leak. But they are bloody hard to get hold of. I have a lot of these and they are also our nursery nappies as I find it best to send the same sort in.
Little Lambs onsize pockets- too big for us and therefore leak. I only have a few but they are not my favourite. They are cheap nappies but good value if they fit. I generally use only at home when I can change frequently.
Baba and Boo-such beautiful nappies but they are bulky and a terrible fit on my DD so leak. I also had to buy the additional slim insert as the ones they come with weren’t right (one insert not enough and two made the fit worse. I want to love them but they don’t suit us.
Motherease quality has nosedived and the ridiculous washing instructions to keep the warranty valid mean they are a massive PITA. Don’t buy in to the hype.
Smart Bottoms are worth a look as are Blueberry.
I hate velcro nappies, poppers are my recommendation as velcro is a bitch to wash and toddlers undo them!
For nights I use Totsbots Bamboozles with a Blueberry Capri wrap. Another bombproof combo for us (DD still feeds lots at night). The Bamboozles are velcro which is irritating but I put up with it as they are otherwise good. Tge wraps are poppers though.
I used a variety of newborn nappies too as my DD was teeny tiny. Close pop-in were the best. More bloody velcro but you need the adjustability on dinky nappies. I also liked Totsbots teenyfit stars, Bumgenius Littles and Lil’ Joey which were all good.
None of the BTP “onesize” fitted DD until she was 5 months old as she was so long and skinny (6lb 10 so not ever so small but she had tiny thighs).
It is best to try a variety and The Nappy Lasy people were so helpful-as is their Facebook and Youtube
