Having a child later in life pros and cons?

I was wondering if I could grab some input for those that had a child later in life, especially after having a special needs child. Did you have a normal healthy child after or a second special needs child?. For those who had a child at 35/41 was it worth it? Or do you regret it?

My partner and I just found out we are pregnant, we both have kids to prior relationships I have 2 to a failed marriage the youngest being special needs & my partner has 1 our youngest is 8.
