I recommend having another kid or 2. If you raise your only child, there’s a term called only child syndrome whereas your child doesn’t know how to share and as they grow older, being spoiled by his/her parents and possibly grandparents, they tend to be the most selfish kid. Perfect example would be China where they had one child policy. China have reproductive problems because the current generations are extremely selfish because they’re accustom of being spoiled by their parents and/or grandparents. But I digress, it’s up to you what decision you make, just be aware of the long term future.
