My partner sleeps a lot of the day. He works 8 hour shifts and will come home and nap for at least 2 hours. Will get a good 7 hours sleep at night. The rest of the time hes just sat looking miserable and yawning all the time. We have 2 DC's who probably get an hours worth of his time. When he has days off the day is mostly focused on his naps and his sleep. If I comment on it he just moans and says he's just tired. In the past he's said he likes having a nap to just get some time on his own when we were having some problems. We are fine now. Is it just him being lazy or could there be something wrong medically? I survive every day on between 4-5 hours and as a mum of 2 do not get the luxury of naps. Before I met him he would easily sleep 13-14 hours a day.
