If you're like me who took lots and lots of pictures of your tot in his newest outfits while opening his gifts, or when he was playing with the box and wrapper (and while his cousin and uncle plays with the toy itself), and after he's fallen asleep, exhausted from all the merrymaking, keep your sd cards now. Better yet, upload them in your laptop and your spouse's PC. And if you're real OC, upload them on the net.
Otherwise, the merrymaking in malls or somewhere else might result in broken or lost memory cards.
Make it a habit to backup your pictures/files. It sure saves us tears.
