Is this ever going to end....

So, it's 3:30 in the morning and I've been up since 2 am listening to Weston cry. I'm trying to get him to sleep through the night, but this is really not fun! I know I should be sleeping in bed tuning out his crying, but I can't.

 He is over 5 months old and still wakes up at least once a night - although we had some good nights this past week where he slept from 9:30 pm until 4 or 5 am. I don't understand why he can't do that every night.

Does it get better???
