I would love to say its doable and if you have too you have too but I would see a massive headache for you both. It's so tough, why aren't there more spots available. Going back to work is hard enough without having to put him in 3 places. Take the long one and hopefully some more spits come up. Also I find consecutive days much easier on them than day on day off day on day off ect. If you change your roster does that help with places available?
