I need some tips!

I had been busy this is the reason why I was not able to post anything here. This is actually my first post in the month of May. Everyday is a busy day for me. Doing house work and taking care of my superbaby makes my day successful yet tiring and it draines all my energy. Sometimes my son will cry and demand to be carried all the time. Take note hes 10 kg now. My shoulder and back are aching.There were times, that he doesnt want to play, and watch his favorite TV show (Baby first) When I am cooking he is in the kitchen with me. holding my legs while crying. sometimes he bites my clothes just to get attention. Ohhh goodness.
Taking care of my baby makes me exhausted and lazy.Do you experienced this too? I need some tips here. Thanks
