When can overnights start?

HattieLove

I'm due in February and SO and I just recently broke up. We are on okay terms and I want to make sure he'll get ample opportunities to see his daughter.

So when can LO spend nights away from me? I plan on breastfeeding but when she can be away from me I will pump. I've seen a range of answers from 3 months to 18 months. I know every baby is different but I'd like a more specific time frame. 

I am by no means looking forward to this point. Until she can spend nights at his place, he'll stay over here with her in her room every once in a while. And I prefer that option over her spending nights away from me. But he would prefer to have her at his apartment, so I want to give him a timeframe as to when that can happen.  

TIA
