Too soon for a second IVF baby?


I'm going through <a href="">IVF</a> treatment for a second baby and I'm having the creeping sensation that it might be a bad idea??

Our 18mo is the happiness of our family, we never knew such love could exist. My partner and I shares the secret that although we love each other very much, it is but a drop in the ocean of the love we hold for our child. Our first child is easy going and reserved, he is optimistic and expresses his toddler frustrations subtly - we are very lucky to have had an easy time.

Looking at our friends with two children, it seems they are worn out and there is absolutely added strain to their relationship.

I read that 3 years is the optimal age between children, as the older has by then formed bonds with other children and other adults. If this <a href="">IVF</a> treatment sticks, our child will be 2 years and 4 months at the arrival of a sibling.

Am I overthinking this, or should we wait?
