Not that I'm not grateful I am but I wish my father in law would stop buying us diapers. Delos doesn't need anymore. He still have two big boxes of unused diapers from Delos' birthday in August. He is almost out of size 3 and by the time we finish these 2 boxes he will be out of them. Not only that, my FIL doesn't buy a brand we like. We do NOT like Huggies and my mil tells him that every time he buys us diapers but he still does not buy Luvs. So idk what to do with these diapers now. I don't want to use Huggies on Delos again just because we have them because that is our problem. We have been using them because they were gifts and unexchangeable due to stores not selling that brand or something. But these are exchangeable but I don't want to do it because then my FIL won't know what or why I did it.
