New baby in the house

We have a new baby in the house! Yesterday around dinner time we took placement of a 3-month old baby boy. I found out today that it looks like he'll be placed with an aunt on Tuesday afternoon, after a court hearing. So we won't have him for very long. I don't know what is more of a challenge - taking care of an infant again, or keeping my own kids out of his little chubby face! They just want to surround him constantly, and I think he gets a tad overwhelmed! He slept ok last - down to sleep around 9 pm, up at 1:30 and 5 am for feedings, and up for the day at 8 am. This afternoon has been a struggle for him - I think he's realizing this is not home, and has been very fussy. But he's good right now - he's cooing to Gretchen while he is in his swing. Hopefully those coos won't turn in to screams!
