A.D.
As much as I would be in your boat totally with wanting to take my child with me, considering the age he is and the routines he has now it seems like the best idea, in my opinion would be to keep him here. He has his daycare, his family, everything. As much as it is going to be such a change for you and him and your husband. I feel like if the exact same situation came up ( I have a 24 month old daughter) I would want to do what you want to do but the best idea would be to keep her at her routine that she knows at this age. I wish you the best with everything. You'll get through it!
