we have one teddy nappy. it has lasted really well- 3 years so far and is nice and soft. velcro isn't what it was but it's been used for ages. it was great to have a microfibre nappy in case of running out- it was almost dry when taking it out of the machine.
i find it not as absorbant and more bulky than say tots bamboozles.
for boosters- i have a mixture- bamboo, hemp, microfibre and cotton (maybe 1 or 2 of each). my microfibre ones are justs the cloth you can buy in the supermarket
we don't get rashes or anything with the teddy nappy, and i only use it at night
Eta if i was starting out again- i would prob get a terry square (?little ewe), fitteds- one cotton (? bimbles/ tots), one bamboo(little lamb), one microfibre (teddy) and then maybe an AIO (?teenyfit) or pocket (?fuzzi)
and some mother ease rikki wraps, nippa and some fleece liners
that would give you a mixture and then you could decide what you liked.
