Sleepless nights

I was just wondering when all this shall pass... Both my eldest were sleeping the night through at baby's age, yet baby's light years from doing so, or so it seems. He can wake up over 8 times per night. I sometimes feel I won't be able to cope, yet others, I feel strong. I know I'll look back one day and laugh at it all but right now there seems to be no light at the end of the tunnel. But because I'm a mom I get through it and I love my baby with all my heart and know that all this time "investment" will pay off in the future by having a happy, self-confident child.
