Decide on a Hashtag
You might turn your nose up at the idea of giving your baby a hashtag or even his or her own Instagram handle, but let me tell you: it's worth it. Having one offers me countless moments of reflection. One click on the hashtag, and I get a stream exclusively of her shots (and none of my ridiculous aerial food pics I'm guilty of taking on occasion). Plus, if anyone else takes a picture of her, I can always tag it and keep it close at hand.
So, if you decide to use one, plan it out well in advance of your trip to the hospital. If you want the hashtag to grow with your tot (will hashtags even still be used in five years?), maybe don't choose #BabyChristopher, as he won't be a baby forever. Or the baby's full legal name, for privacy purposes. Or something too long or too difficult to remember, both of which will make it less likely to be used. Also, make sure it's not already a popularly used one, as you'll have to scroll through hundreds of unrelated pictures every time you want to dig up a photo.
