Baby Bits turned Mischa Milestones

Mischa is going to be 6 weeks old on Tuesday. I've read that a growth spurt is coming up; I can just imagine what that entails (feeding every 2 hours or less, sleeping...more? or less? She currently spends the days awake more than asleep). She already reached some milestones in the past 6 weeks: smiling! lifting and turning her head during tummy time, fattening up! And last night she gave Dale and I a treat and slept for almost 4.5 hours. Now that is a major milestone! I hope more long stretches of sleeping is part of this upcoming growth spurt.
