I think you should just not take any pictures! HAHA Tough situation good luck solving the problem. Actually raising twins should be slightly harder I think!
Congrats

Congrats on the twins, mine are 12 now and I do recall those times What worked for us was color codes, it is a lot easier with boys I have to admit. We never had much trouble telling them apart (unless they were asleep), but looking back at those photos, I can figure out how we did tell them apart if it wasn't for their clothes colros.
