Yikes

Tyson has been asleep ALL morning in the swing. He woke up at 7 am, ate, and then screamed for 1 hour! I finally put him in the swing so that I could remain sane. He promptly fell asleep and has remained that way for 3+ hours. I'm wondering, does this mean he will sleep tonight????? I hope so, last night he slept 8 hours in a row! How about a repeat performance, buddy.
