What are your kids triggers?
We all know when our kids are probably going to get grouchy. It's different with each kid though. What might make one grouchy may not bother another kiddo.
With my daughter if I get frustrated or stressed out she totally reacts to it. Or if I ask her to clean, hehe. She's getting better with that one though, thank goodness.
With my son it is when he is tired. He gets so grouchy when he is tired or bored, but mainly tired. This is a big reason I try to keep him on a sleep schedule even though he is 10.
What about your kiddos?
Erik's son is grouchy when he's hungry. I'll remind both kids that they need to eat before we go and that it'll be at least 2-3 hours before we all eat a meal again. I'll suggest that they pack a snack and bring a bottle of water to take with them. When they don't do this and Erik's son complains about being hungry, I remind him about my suggestion and that it was his choice to not pack a snack. I don't give in and buy him something so I say no to his request of buying him food. May sound harsh but it teaches him to be responsible next time and to make better choices.
Our daughter who is four will get set off by alot of things. Mainly the word no and getting in the bath. She throws her little silent not so silent tantrums, grabbing her face with her fingers, sighing super loud, purposely as slow as a turtle. I just keep going like I don't see it and handle what needs to be done, then afterwards adress it.
My step-daughter, Jaina, gets grouchy whenever we tell her what to do...even the simplest things. She is nearly 12 so I am think it is puberty.
