My daughter is 12 weeks old tomorrow. Her dad is active duty military and is going on a mini-deployment. It's very rare that we get asked a preference for deployment date, but it's happened. The 2 options are for him to leave when she's 5-8 months, or 8-11 months. Is there a developmental or psychological impact reason to have him choose one or the other? We're hoping to pick the time-frame that would be best for their bonding and attachment.
