I love Napping

Re
Prior to becoming pregnant I loved partaking in a good catnap after work, which caused my SO to be generally annoyed. He never naps and thinks that the need for a nap is made up. I'm 19 weeks and I've never needed naps more. I'll come home from work, nap for 2-3 hours, eat and hangout, then go to bed for 7-9 hours of solid sleep. 
On the weekends I'll wake up, eat, hangout, and nap for 3-4 hours. He thinks I nap too much, I'm trying to tell him that growing a baby has left me with little energy. He thinks I'm using pregnancy as a convenient excuse since I was a notorious nap queen prior to becoming pregnant. 
He's starting to wake me from naps now. My immediate response is to curse and whine, which he finds 'appalling' 🙄 But I just need to nap. I'm enjoying naps while I can because once the baby arrives that's it for naps. Is anyone else getting crap for napping?
