Another baby at 44? Yes or No

So I am recently divorced and have been blessed to find a new true love. He is everything I have wanted. We are in love 100%. He wanted to marry and I am so thrilled with that, he is also Catholic and wants  baby. The kicker is I am 44 with 3 daughters -22-20-and 14-
He is 54 -we are both financially secure and prettyhealthy. Is this an absolute ridiculous idea? I have thought about how old I would be when the child is  10 and 20 and stuff like that all of that's pretty obvious any other thoughts?
