My situation was different Georgie was 2 when my son came along. My husband and I talked about what if Georgie has a difficult time adjusting to Isaiah and we both knew that giving Georgie up was not an option period. Whatever it took we would make it work. Isaiah is 5 and I am convinced Georgie has finally come around to the fact that Isaiah is here to stay lol. It takes time and patience but it can work. I can't imagine not having both my boys
Lynzy gave you great advice and I am sure others will as well. Good luck!
