So my son has been a great sleeper since he was born. These past few months he will get up about 430 am and play for about an hour or so and then go back to sleep. He never cries, just plays. This includes fake coughing, growling, leaping back and forth in his bed & talking. Does anyone else LO do this? Also I am not complaining at all. I know I am very fortunate to have a good sleeper. I just dont have any mom friends and would like some input on this.
