Congratulations!!!!! My twin Granddaughters were born 12/27 last year. They also are identical. Tell your daughter to see if she can find a 'Twins or multiples' group. They have a lot of information to share like buying 2 of the same car seat, highchair, etc. My daughter dresses the girls similar but with one having the darker color clothing to help telling them apart. Twins/multiple groups also have great resales with everything from baby equipmet to clothing and toys.
