This is the hardest part of this stage (9, 7, 5) my 9 year old annoys me the most because it is SUPER obvious things like "what are we having for lunch?" as she watches me pull the tuna and bread from the fridge.
Part of it is is her temperment, she needs to know every detail and she likes to be *told*, like it validates the experience for her to hear some one else say it.
Either way I am really working on my patience and trying to turn it back on them and have them do some critical thinking. I am also trying to be sure I tell them that I need some quiet time in my head BEFORE I am ready to snap from the 15th question in a 5 minute span (and it's always when I am just trying to complete a task before the toddler takes some thing apart or starts shrieking for me to hold him).
It is a lot.
