OP your son will.provide you with awesome memories. I can still see the tiny baby in my arms, the indomitable force of blonde, chubby energy that was his two year old self, the nervous chap in his grey shirts and socks on his first day at school, and all the looks that followed.
Not forgetting the experiences of, seeing his baby sister for the first time, the joy at his first try, his pride at getting the best cricketer award, aged 7, the day he phoned me with his IB results and I stopped the traffic on a busy London high street, waving him off for his gap year in NZ and welcoming the young man he had become 9 months later. (Add in the broken arm, ankle, nose, first time he was dumped, etc).
It was a joy to watch him take his next steps. From being ready to walk, start school, go to uni, getting engaged and soon to be married.
Where I would ask you to catch yourself a little and get things in perspective is around the hurts that others have suffered. The parents whose child is disabled or becomes gravely ill and the child who is lost. I lost DS2 at 27 weeks after a few very short hours. I have no memory of him at 1 but I have my imaginings of my quietet, more sensitive, darker, boy who chose music rather than sport. Just be glad op that your ds will likely give you a lifetime or memories rather than imaginings. DS2 would be 26 this year - I so wish he had reached 1 and I'd been able to see him develop into a boy and then a man.
