We're at the stage of having DH's youngest GC weekly, and my biggest struggle is that he would (if I didn't fight it)just say yes to EVERYTHING rather than have to say no to anything! I've always felt that, like the Army Generals of Old...you need to pick your battles, but once you've committed, you just have to stick to your guns!
I never immediately say no to stuff, I think is it worth committing myself to, because once I have, I stick to it like glue! DH cannot handle the pleading, the begging and downright tantrums for the sweeties/whatever that are not allowed because lunch wasn't eaten...and he would if not stopped, just cave in EVERYTIME!!! It's all very trying isn't it?!
