C.S.
I have an 11yr old daughter and it was a tough decision for me to have another baby being so far apart in age. Let me tell you, it's the best decision I made. She is awesome with her sister and at 11 - they want more responsibility and I think your daughter will really enjoy it. My husband is not the father of my 11yr old and I always wanted to have a child with him and after a few years of deciding we took the leap. He's 43 and I am 31 so that's great your husband is all for it at 45 - that's still young enough to enjoy having a baby. You will really appreciate the help too if your daughter is willing - $ is a good motivator too as they are too young to work - helps them get what they want if they save and work a bit for it helping out. Good luck!
