Split custody for 3 children

I live in Virginia. I have a 5 month old daughter, two year old son, and 8 year old son. Since my daughter has been born my husband has been out of the house. He will occasionally pick up my oldest son, 1-2 week and spend a few hours with him, much less often he will take both the boys 1-2 times a month and returns them at night. He has no interest in our daughter hasn’t changed one diaper, fed one bottle, and has spent less the 30 minutes of time with her since being born. His work schedule is changing in August and he is saying he wants our oldest during the week since he will be in he better schools district, our middle 50 percent and nothing for our daughter. I feel like he doesn’t want them at all but of course he doesn’t want to pay child support, I think they all need to stay together majority of the time. What do you think a judges take will be on this, his argument is he can’t see them much right now because he is in training school, however it is only a regular 40 hour week in which he is getting paid for. How will the judge feel about him spending no time with our infant at all?
