Sleep

Does it ever get better! I'm so tired! She's up every 1 1/2 then won't take but 20-30 min naps. So basically I'm waking up right when I finally get to sleep, I take awhile to get to sleep. I try to nap when she does but can't fall asleep that fast. My husband can't help on weekdays and won't help on weekends. He doesn't understand how tired I am. I'm starting to get frustrated and angry.
