First of all, congratulations for them on having a child! That is wonderful news and worth of celebration without end (even though the end will probably come when they pass out from exhaustion due to midnight, 3:00, and 6:00 feedings :)).
As for the rest, that's unfortunate and frustrating. I hope it will be like @whatsup suggested, and that this is only temporary so he can have a bit more time at home.
Regardless, they really should have allowed a bit more time at home for him, especially if the powers-that-be have had kids of their own. They should really get it.
Anyway, from my family to his, pleas pass on our warmest wishes and congratulations. We wish them all the best and that they are able to get through this and be all the better for it.
