It's been 7 months, but whose counting?

Just got back from a dreadful doctors appointment. Two babies equals 6 vaccines and lots of crying. I survived, not that I'm the one that experienced any pain! The doctor is concerned about Sebastian. Sebastian has low muscle tone and is developing a bit slower than an average 4 month old baby. Should I worry? No. What is the point. My son is perfect. His personality could charm the pants off anyone. He's gentle, loving, flirtatious, smiley, kind, and loves to laugh. So what if he gets a little tired during tummy time. I know one day he'll crawl. I know one day he'll walk. Those things will come. We will teach him. But you can't teach someone how to be innately good. You can't teach someone to have charm and personality. If he wasn't able to laugh, then I'd worry. So he's 7 months old, but who's counting? He'll become his own little person in his own time and I'll be there cheering him on along the way.
