Be prepared
I've never been all that enthused about babies, to be honest. While my own kids were adorable infants (of course), I enjoyed them more when they got a little older, around two.
This weekend, though, we're back to infants, with a vengeance. Joanne & I are grandbaby-sitting 9-month old twins, Bronxton and Phoenix.
Here we've prepped emergency supplies for the night. Each has a bottle of water, first option if they start crying. There are also bottles of formula if the water doesn't do the trick.
As it turned out, this was a pretty good night. Phoenix slept all the way through, to our surprise. Bronxton, on the other hand, was up for more than an hour in the middle of the night. Neither of the bottles were able to calm him.
