Our DC is happy and balanced and we do ensure he has other children around to take account of the fact he is an only child. He has never asked for a sibling
do not assume siblings will be link and Enid Blyton novel, all full of love and joy. They arent. Your son is 9, so nearly 10? and almost at transitions stage to secondary. It is half a generation difference. They will have nothing in common - I know - there is that age gap with myself and my sibling. We have nothing in common, not even brought up in the same town (parents moved) no shared schooling or memories. In fact he left home ASAP to go into the military and I dont rememeber him until I was 14.
Both of us quite liked being an only child.
And I dont want to be appearing rude - but your age is where problems begin to occur. I wouldnt take the risk of having a child with a disability of some soert, which will undoubtedly fall to your elder son when you and DH pass away. That is the harsh reality of life.

Is pregnancy at 40 high risk?
Due to advances in technology surrounding fertility, pregnancy, and delivery, it’s possible to safely have a baby at age 40. However, any pregnancy after age 40 is considered high risk. Your doctor will monitor you and the baby closely for the following:
high blood pressure — this may increase your risk of a pregnancy complication called preeclampsia
gestational diabetes
birth defects, such as Down syndrome
miscarriage
low birth weight
ectopic pregnancy, which sometimes happens with in vitro fertilization (IVF)
How does age affect fertility?
Advancements in fertility technological have been a driving force in the increase in women waiting to have children. Some options available to women include:
infertility treatments, such as IVF
freezing eggs when you’re younger so that you can have them available when you’re older
sperm banks
surrogacy
Even with all of these options available, a woman’s fertility rate does decrease significantly after 35 years of age. According to the Office on Women’s HealthTrusted Source, one-third of couples after the age of 35 experience fertility issues. This may be attributed to the following risk factors that increase with age:
fewer number of eggs left to fertilize
unhealthy eggs
ovaries can’t release eggs properly
increased risk of miscarriage
higher chances of health conditions that can impede fertility
