HUGS! The people at the library today probably think I shouldn't be allowed to have children because I was so short with them and looked like I was on a war path instead of enjoying our time there. We definitely all have bad moments as parents, but you learn and grow from them. Next time I'm in a nasty mood we won't go to the library.
My parents spoil the kids too and sometimes I get upset because I'm the one who has to deal with it (whether it be sugar or toys). My mom was so mad at me a couple weeks ago because I gave away a toy that she bought for Cohen's birthday because he was misbehaving (long story). But at the end of the day, I AM THE PARENT, and I decide what is best for the child. If they don't want me to give away the stuff that they give him, they can keep it at their house (basically I was sick of him not helping me pick up his toys - FYI since his toy was given away he's been a new child). Likewise with your mom, you can tell her that she can give him all the sugar she wants as long as she's prepared to watch him over the course of the next 12 hours while it works its way out of his system.
I'm just sort of venting my hormonal pregnant attitude in your post Jennifer. Feel free to ignore all my nastiness
