I think you do need to parse in time for rest periods. There hasn't been any in your plan so far, has there? Everyone in the house should know this and respect those times for you NOT to be bothered with anything. I think 3 rest periods are in order. Just wind down what your doing and start to consider them part of your day. You certainly can put some things on the back burner and move yourself up to the front burner. It's important, you're important!!
