Heidi has been up it seems like ALL night the last couple nights. She is still super happy during the day and not sleeping any more than normal, but she just isn't sleeping at night. Is anyone else's little one having a change in sleeping at this age?? I don't know if it is a growth spurt, teething, or just excitement at her new ability to roll onto her side? She just screams when I lay her down, but is fine during the day during naps... she will only sleep if I am sitting up and she is resting on my chest... I'm soooo tired.... Hopefully what ever is going on sorts itself out soon.. I really miss my all night sleeper.
