and welcome to the Tree. I use pockets a lot with my DS. He's 22lbs and wears larges with no problem. My main pockets are Bumgenius which, stuffed with their accompanying microfibre inserts, easily last 2-3 hours on my medium-heavy wetter. Other inserts that work well are a combo of bamboo and hemp (Easy Peasy hemp boosters and petite dessous bamboo supersoakrers).
