Momnesia

I know most pregnant women, include myself, have heard of, and/or experienced "pregnancy brain." This is the phenomenon where you suddenly have a very bad short-term memory, like forgetting where you put your keys or whether you turned the oven off before leaving the house. But no one has ever told me that I would still experience this after having Scarlett. To this day, I still have "momnesia" occasionally. I often find myself walking to the bedroom to do something, but by the time I get there, I can't remember what it was that I was going to do. Or, I'll tell myself that I need to do something later in the day, and that task gets completely forgotten. The best example was when I attended a friend's wedding when Scarlett was about 2-3 months old. This friend was also a colleague so a few other co-workers were at her wedding. At that time, I was still on maternity leave so I haven't seen my co-workers for about 3 months. I greeted one of them, and for the life of me, I could not remember her name. So I had to resort to saying, "Heeyyy, how's it going?" Of course a couple of hours later, I finally remembered her name - Laura! How could I have forgotten?! Recently, I've been hearing ads for these brain exercise games for older people to keep their minds sharp. I often wonder, should I invest in some of these games before my brain turns into mush?

When does momnesia go away?
