busy baby

Oh my gosh ladies... I am exhausted!! I work 40 hours a week and with my little soon to be 18 month old, I’m burnt out. He is so so busy. He has always been a busy baby. We cannot even go out to eat because he can’t sit long enough in the high chair. When we are home, he is into everything, I mean everything. He wants to know how everything In the house works, etc. my mom said I was not like that at all, I just sat down and played with a toy. My son sits down maybe 1 hour out of the whole day, the rest of the time he is running Around. It’s tiring! I hate to be that Mom that is “too tired” to do anything with baby but I really am! Please help.
