Keeping Up With An Almost-6 Years Old

I'm 35 years old and I'm a single mother to a 5-year-7-month-old energetic boy. It has always been the two of us since he was conceived. That been said, let me just say that our relationship as mother and son is I guess weirder than most people. My son is extra-attached to me simply because from the moment he has seen light in the world, there was just me as his parent. Of course he was loved from the very beginning by my whole family and friends.
His world revolved around me and mine revolved around his. Maybe that is still the case, though we moved back home to live with my mother and 2 younger brothers (going to college, but still lives at home) more than 2 years ago. Moving back home to become a work-at-home-single-mom was made mainly to save my own sanity so to speak.
Looking back now, our life then was just crazy really. I worked an 8-5 job that at times had to extend late and to the weekends while i shuffled my young son to various sorts of daycare and nanny arrangements. There were times on weekends I had to bring him to the lab where I used to work because I just couldn't afford a nanny or daycare on weekends.
Since then the two of us have conquered too many hurdles. Though we are still both working on many things, we each are a work in progress. It doesn't end I guess, well maybe until he leaves for college. I think that's when I can breathe more freely. He he.
It's a long way to go. Until then we'll gonna have to go through the ups-and-downs, the love-and-hate moments and the other stuff that makes me smile and grimace all the same time.
On thing's for sure. He loves me to death. I love him to death. We have that, and each other always. Even if sometimes I want to fast forward the years to 20 years ahead, as any mom would agree with me. You have those moments too from time to time. Then once you see the big smile plastered on you child's face, and the big hug he gives you at the end of the day – you just shrug a tired shoulder and savor the moments while he's young.
My only complain really is I that I can't keep up with my boy's energy.
