Wow! You pretty much are our story! We have two boys. When my 2nd was born, I was diagnosed with a heart condition that prohibited us from having additional children. We adopted a daughter when they were 4yrs and 2yrs. My husband was VERY concerned that he would not be able to love her the way that he loves the boys. First of all, the boys accepted our daughter there was nothing unusual about it. Oddly for us, we had not even mentioned adoption to them, as we expected to wait at least a year. When we got "the call" 3 weeks after our Home Study was completed, we were quite shocked. Since she was born in Idaho, there is no revocation period after the birthmom signs. So ... we decided to tell them we were just going on a little trip (to protect them emotionally). We called them the night before we flew home (after the papers were signed). They acted like it was totally normal
We expected a huge transition, and, honestly, their was virtually none. As for my hubby ... hmmm ... she has him wrappped around her little finger. He is madly, deeply, unquestionably in love with her! Hope that helps! Sorry! Just realized I double posted on this topic.
