A few months ago I had to restock almost my entire supply of daily wear diapers. I can't remember the exact cost, but I think it was in the range of $500.
4 cases of Abena M4 (144 total), 2 cases of Megamax (80 total), 1 case of Depends real fit (56 total), wipes, 1 case of Goodnites bed mats (36 total), and rash cream. That is well over 300 diapers if you count the bed mats. This definitely can be an expensive hobby.
No hesitation, but I did cringe when I saw the credit card statement. This is how I prefer to spend my money and as long as I can afford it, I am going to be padded with the best diapers money can buy. This matters more to me than buying the latest tech, expensive meals, having a nice car etc.
