Brandon is 5 months old

Brandon turned 5 months old on May 14th.  He has definitely grown since last month.  On May 14th he weighed 15 lbs, 14 oz.  He is working on rolling over.  He's getting close, but can't seem to get over just yet.  He's also working on those teeth and already has two bottom teeth!  He drools a lot because of the teething and he likes to chew on his hands.  He's such a happy boy and smiles a lot so I see those cute little teeth every time he smiles.  Brandon loves attention and loves when someone talks to him.  He gets the biggest grin!
He is eating 5 oz every 3-4 hours.   He usually sleeps well at night though for the past couple of nights he has been waking up at 3 or 4 am hungry and wanting to eat.  This is not like him.  I think the formula is just not enough for him anymore.  He is just needing more and I may with his doctor's approval add rice cereal to his bottle.  We moved him out of our bedroom into his crib in his room on May 16th.  He did just fine with the transition.  He is such a good baby!  Love this boy so much!!
