My children are 18/11/3 and one due in June I do like the space between....it was particulary good with 2/3 who are very close.
My daughter (who is now 20) and my 3rd child (who is going to be 14 in 3 weeks) are 6 years apart. (Then there is an older brother who is 22)...so 8 years apart as well.
They did GREAT when I had my son. They played big brother and big sister to him to the fullest. Always kept an eye out on him and played with him. It was great. We never had any issues and now that they are older...my 13 year old does EVERYTHING with his brother. They are VERY close.
Now I just had a baby in April (who is 5 months old) and she is the love of my 2 older childrens life. Couldn't ask for better brother and sisters.

I am currently pregnant with my 4th child and my children's ages are as follows: my oldest is 12, second oldest is 10, and current youngest is 3. There is a 9 and 7 year difference between my oldest 2 and current youngest. I have to say that it really is great. The older two are very loving and responsible with my current youngest. I was a little afraid of the difference, but it really isn't a problem. I am due with my 4th in 3 weeks and my 2nd oldest, who is 10 and a girl is super excited about this baby as she will now have a sister! My 1st and 3rd children are boys.

I wouldn't be very nervous about the age span, but remember that when your new baby will be seven your daughter will be 14 and she will be doing high school stuff and her own thing.. it can either go 2 ways, they will be inseparable or they will be opposites, I have a 10 yo girl and a 15 yo girl and they dont do anything together but I also have a 17 yo boy and a 18 yo boy and they dont get along either. so I dont think its an age thing I think its more of what family values they have, my kids are more selfish then they are all about the family and I haven't a clue where they got that from because I am totally about family comes first. I will say that they are all lovable towards the baby, he gets love from all the kids. My husbands two kids are very close, and do all kinds of things together they are two years apart. but they are army brats so maybe that has something to do with it, because army kids tend to move a lot and that sometimes only leaves each other to count on.
Assuming we survive the miscarriage stats, my youngest will be 9 when this one's born.
You know, it's funny, my DS said the he would prefer a brother because boys and girls fight too much! He is happy about having a baby, but even suggested that we give the baby up for adoption if it turns out to be a girl! ROTFL! Seems like it's probably a developmental stage. :)
As far as the sleep issue goes, I'm hoping you get a sleeper too! DH and I were recently talking about the baby vs DS. We are hoping they are similar in many ways. DS is a good sleeper, eats anything we put in front of him, switched from breast to bottle to breast easily, etc. What WILL we do if the new baby doesn't do those things? Adjust, I guess. :)
DS kisses my belly every day, hugs it, and talks to the baby. He really can't wait to meet this little one. He also is good with babies as well. I think your daughter will be fine. :) Good luck to you!Tamie
