I don't blame you for being hurt, I would be hurt too. I don't think that parents today teach their kids respect anymore. But if your sister in law didn't send a thank you you probably wasn't surprised with the kids not sending a thank you. I am very fortunate that both of my kids have taught their kids respect. We have bought baby gifts and wedding gifts and we never even got a call, card, or a thank you. UNREAL!!!! Our parents taught us better than that. I am sorry for your hurt. Don't go out of your way for those that do not appreciate such beautiful work that you put into your gifts. God Bless You Lura
