Kudos to you on being so strong throughout everything...My only advice to you is one my mother gave me. Take a small stuffed animal and try to have it with you all them time(while your home) to get that mommy smell on it - maybe tuck it in your shirt at night - then leave that with him so he can smell you...I did something similar with my babies, but I would take off my night shirt and roll it up and leave it near them when they were small so I could leave them with daddy - to even go to the store...this did help them not melt down...my kids were younger though then 6mon.and so I'm not sure if it will work.. and on another note I did have to leave one of my sons at daycare once when he was 3months old for about a year...he did adjust and I just made sure I kept a good relationship with the employee watching him..they did provide a time sheet of how his day was and that did help...Sometimes the transition is worse for mommy than it is for baby - hang in there.
God Bless
