Oh sweet, sorry to hear this.
All I can say is that your little one is only 2 months old, not the time to be making big decisions like that! Your DH may just be feeling a little overwhelmed with all the things a new bub brings to life, give it some time and he may come around.
I know that when my DS was that age both DH and I were dead against having any more. Now DH is the one asking if we can have another, but I am not sure!
Make sure he doesn't do anything final like having the snip and give him a little time to adjust to parenthood.
Hope this helps
