Almost 30w with our last child

Jamee • 27. Married to the love of my life. Three amazing beautiful blessed children and one on the way due in June 2015.
My husband and I have three children (5yr old boy, 2yr old girl, 11m boy) and are expecting our fourth and final (a boy) June 14th. I'm excited to complete my family, as I haven't had the easiest pregnancies, but I'm still so nervous about knowing this little bundle is for sure our last and I won't be going through this process of creating another life again. I kind of want to do something special during this last pregnancy in the last ten weeks, since that is it. Any suggestions??
