Dr Mom
If she's happy - it's normal for her. If she's fussy - then something is bothering her - could be teeth, not enough in her stomach to stay full, ear problems, indigestion, growth spurt causing muscle aches, etc. Your observations and intuition will know better than anyone. Those first couple of years can be exhausting - especially if you have more than one. When the baby finally gets to sleep, the others are waking up. Years ago, I had 7 children which were 8 years old and younger - I thought I was going to live my entire life exhausted and smell like sour milk and urine for the rest of my life. However, this too will pass - the trick is to cherish it while you have it because they will grow up faster than you can imagine when you are in the middle of it. Good Luck, Dr Mom
