do not be in such a hurry.   Do some research.   At such a young age a child needs to be with their mother more than they need to learn socialization. In fact, they do not socialize very much at all at this age.     If your wife is not wanting the baby to go to nursery and you can afford to have her home, let her decide.   I am an educator with  4 children and only sent them to nursery when they were 3 or 4 years old.   Before then I simply arranged occasional play dates with others,  mommy & me classes, etc.
