OMG I am so confused *shakes head*

And any suggestions on whether the Microfibre or bamboo boosters are better?

Bamboo - absorb more, no compression leaks but slower drying
Microfibre - faster drying, but prone to compression leaking.

Bamboo for me.
FWIW my 6 monther is so chunky she's only just squeezing into her Ms and is only a smidge over 6kgs (and they're supposed to go to 11!).

Bamboo for me too.

My girls (6lbs at birth) started in mediums at around 3 months old and my oldest was in them until over 3 years old my youngest is 11 months and on the loosest snaps.

My DD burst out of those mediums at around 5 months! And she was not that big.
