Poor thing is probably sleep deprived, exhausted, overwhelmed...I remember all my days and nights ran together for the first 9 days. I was flabbergasted when my DH told me the date and I had "lost" time.....
My son was 7lbs and my daughter 6lbs....I thought that was big! So funny, I don't remember the pain...just the everlasting joy of hearing that first little cry.
