Wake up at night

If you haven't seen the boys in a while you don't know that Keelen is much smaller that his brother Estin about 3 pounds less. The doctor told me the start waking him up at night, like every 3-4 hours, so I've been setting my alarm to wake up at 1 am and 5 am. It really stinks when you have to set your alarm to feed a baby. They were sleeping thru the night and I loved it. I guess it is the best thing for him. He really seems like he likes feeding at night. In a couple weeks we will see if he gains weight. I hope so!!
