I'm bad at guessing if Ethan is warm or cool enough. I've just been putting him in a footed sleeper and that's it. We don't have the air on. If it's warm I turn on the fan in his room.
DD sleeps in a t-shirt and her swaddle sack. If the air is on and it seems cold, i'll throw a light blanket on her lower half, if its really hot I omit the shirt.
Justin sleeps in a onesie most nights. If it's a little cooler I'll put his baby legs on him and some socks. On nights that it's cold he wear feetsie zip up jammies. I cover him with a crochet blanket every night.
Since it's been so cool at night, we've actually used light fleece footy pj's. Other than that, light footy pj's or 2-piece pj's. His feet tend to get really cold (just like his mommy's), so we like to keep his feet covered. We've covered him in fleece blankets since he was a couple months old. I've found that if he is cold, he'll let us know.
Re: what does your LO sleep in?
I'm probaby a bad guesser too. G is in a light footed terrycloth sleeper and s/s onesie tonight.
