New parents worry about every little thing that happens to their infant. One cause for concern is excessive sweating. Most new parents don’t expect their infant to sweat at all, much less profusely. However, it’s not uncommon for babies to sweat when they are in their deepest sleep. Shockingly, infants are more likely to sweat profusely during their deepest stage of sleep than adults or older kids.

Keep in mind that sweating is normal, but excessive sweating could mean there is a problem. That is not always the case, but in some cases babies with sleep apnea or congenital heart problems may sweat excessively. When a baby has an infection it’s possible to sweat profusely, too. In these cases the baby may be working so hard to breathe that he begins to sweat.

Another cause for sweating in babies is overheating. In fact, SIDS may be caused by overheating so it is important for parents to ensure their little one is not too hot. The room baby sleeps in should be between 60 and 70 degrees, which is much cooler than many parents initially consider. Babies should not be overly bundled, either, because this can cause overheating. It might seem like a good idea to put socks, hats, pajamas, blankets, and more on baby, but over bundling can cause your baby to be too hot.

Most parents assume they need to bundle baby up, but it is actually recommended to dress baby in the same amount of clothing you would be comfortable in if you were to sleep without covers. Keep in mind that if you are too warm then your baby probably is too warm, too. If your home is cool and your baby has on a onesie or little clothing yet still sweats you may want to talk with the pediatrician.
