Question for moms who have/will have a summer baby: did/will you put your newborn in the long-sleeved sleepers? We've received several but I'm hesitant to put her in them once she gets here because I'm afraid she'll get too warm. It averages 100° here daily and it's only going to get warmer. I'm a little more comfortable with the thought of putting her in the cotton ones she's received rather than the flannel or terrycloth like ones, but I'm still iffy.
