I started out with MEOS cotton, but my hunk of chunk is short and round(like mama, I'm afraid! LOL!) and 3 months ago we switched to Bamboo Sandy's for a better fit. I'm still using the cotton liners though, and he's a really heavy wetter so we double them overnight. I'm going to buy more liners since we go through them so fast, but am wondering if Bamboo liners are much thinner. Is it worth the extra money? If they are thinner, I was thinking of triple-ing them. Does anybody else do that? Or should I use something else altogether? He's just soaked all the way through, waistband to waistband. Just sopping wet. He sleeps through the night, 10 p.m. to 8 a.m. and is 9 months old.
