IMO, when I really think about the phrase "days are long, years are short", it seems like what it's saying, or maybe it's a more depressing way to interpret it, is that "you're not doing anything special/memorable in your days" -- hence the days feel long, but after they've passed, it feels short because there wasn't anything in particular that was memorable to the parents. However, do keep in mind that a lot of everyday experience like walks in the parks that are nothing special to the parents, are very special for the kids. We have a two year old as well, and it certainly feels tough -- it's not like you can travel the world with a toddler (at least, it's out of our abilities range, haha. Some people can do it, I'm sure.), so it's all about living the everyday life (for now, until they're older) and making the most of it. SIP doesn't make it any easier too. Try to at least make the weekends interesting! Park walks are always possible, and a lot of outdoorsy nature type places are possible to go to also, just don't go to the super crowded places.
