In our house we have a ductless AC system, but we do not have a unit in Charlotte's bedroom. The past few days its been 80+degrees in NJ, so the house is starting to get hot. While the rest of the house is nice and cool, Charlotte's room does tend to get hot. The monitor says its 78-80 in there, but I've never found the monitor temp to be accurate. I would say its probably about 75ish in there. I'm concerned though what is going to happen in the middle of July when its day after day of 90+ temps. We do have a fan in there, I put it a few feet away from her crib. So far, she sleeps perfectly fine, so maybe the heat isn't bothering her? I'm hesitant to put a window AC unit in there because both of the windows are very close to the crib. What have other mommies done in the summertime? Will just the fan be enough all summer? I dress her in a short sleeve onsies and a sleep sack that is very thin, just like a sheet.
