I agree with keeping him in daycare. My son was 2.5years old when my daughter was born and we kept taking him to daycare, two days a week.

He didn't like it if DH was home from work but didn't seem to notice that I was at home.

I am going back to work when DD is 9mths old and I think it will disrupt him less when I go back to work because things won't change for him again.

All you can do is see how it goes and take it from there.

Personally, I cherish those two days with DD, because she gets one on one time, which she will never have again when I go back to work and he had 6mth fulltime of it.

Goodluck!
