Mine started school today too after a 2 1/2 week break. The break went fine, AS 9 y/o DD was great and REALLY enjoyed her Nintendo DS she got for X-mas. Today was fine- I was home with the new baby and the 4 y/o until 12:30 then 5 y/o came home from Kindergarden and things were still fine- he and 4 y/o played nicely and watched a video while the baby napped, DH worked(he works from home 99% of the time) and I went out and took down the Christmas lights while we have a break in the nasty NorCal storms. Then 9 y/o DD came home. Can I just say that after about an hour I wanted her to go back to school. UGH! She was whiney, demanding, bossy, and just plain mean and rude to her brother and sister. We barely avoided a meltdown, but I know if I had pushed any of her chores on her( I ignored them today) that she would have gone over the edge.
Thankfully this will only last a few days until she gets back into the normal routine. It REALLY doesn't help that she's got a cold bug too. Ugh!
