work from home full time

I'm going back to work in July or August. I found a nanny to watch my son at her house 3 days a week for 5 hours a day. She is less then 3 miles away. She will only be watching him. I'm still torn if I'm ok with dropping him off and him not being here at my house. He will be almost 3 months old. What are your thoughts? I originally thought having him at someone's house is easier since i work from home so I don't feel restricted in my own house, now I get upset thinking about it. Just need some opinions or advice. I'm a recruiter and my job consists of emails and phone calls majority of my day. The calls with candidates I can usually control and schedule at my convenience. Thanks all!
