Hey, I used the Tots Bots Bamboozles with my LO and found them really good. You need to change the nappy after each use, although the wrap can be used again unless its soiled. The liners are just like tissue and catch any solids so they can be put straight down the loo.
I have 15 size 1's and that was sufficient for us. They can take a while to dry if you don't have a tumble drier (we don't) so we had a 2 day rotation.
Day 1: Used 5 nappies (10 Clean left)
Day 2: Used 5 nappies -(5 clean left) Put all 10 dirty nappies in wash in evening and hang out to dry on airer
Day 3: 5 remaining nappies worn (10 Clean nappies drying)
Day 4: 5 nappies worn (5 clean left) Put 10 nappies in wash
and so the cycle continues! ~(Hope that makes sense!)
I have 2 spare packs of the regular Rainbow bamboozles for sale (I thought 15 was sufficient, and if I used more there would just be dirty nappies sitting for longer in the nappy bin) 5 nappies and one wrap in each. PM me if you're interested.
Also, the tots bots wraps aren't great (although I heard that the fleece ones were ok?). I always use Motherease wraps. I prefer the Airflow, but thats just personal preference. I think 5/6 wraps is probably fine, because they dry very quickly and you can use them the day after washing, so no down time.
Hope that helps!
PS I don't use cloth at night
so you may need more if you intend to, people are always saying how good bamboozles are when boosted for night time use.
