I would suggest getting a sitter for a couple of hours while your husband is at work and spend enough time truly resting and during your meal times eat with your son. since you are a SAHM your health is very important k. keep what your doing with your son and communicate with him and you will do just fine. I have had 2 more surgeries with my daughter and she has always been very helpful. She sleeps at the bottom of my bed and watches tv plays games and read while I rest and we dine on goldfishes and vienna sausages most of the time.
