Sounds familiar. Mine would always ask if she could help and then instead of doing what I asked she would go find DH and start helping him by raking leaves, skimming the pool etc. When I had my third baby in four years she came over and went with him to the grocery store "because he needed help" buying two bags of groceries. Meanwhile I was home breastfeeding a newborn and trying to wash a 2 and 4 year old in the tub at the same time.
