Other Tips To Keep Baby Warm:
Keep a Washcloth or Towel on Them During the Bath
When they’re really little, you can keep a damp washcloth on them or wrap them up in a towel during bath time to provide extra warmth. Yep – it will be a completely drenched towel, but if baby stays calm, it’s worth it!
Use a cup or rinser to add more warm water regularly to keep it a good temperature since it can cool down quickly, but some babies prefer to be wrapped up and it can help keep them warmer. For baby’s that hate bath time, this can be a game changer!
Have a Big Towel at the Ready
Okay, so keeping a towel at the ready certainly isn’t a game changing tip. The real part of this tip is to have it be bigger than you think!
I swear, in all my nannying years, the towels always seemed way too small. I just wanted to wrap them up and keep them bundled and dry until we could get into jammies. But more often than not, limbs didn’t make it in the towel, and little one’s were shivering.
When they’re reallllly little, this might not be as necessary, but once they start to grow even just a bit, skip the toddler towels and get regular sized towels!! Your little shivering guy or gal will thank me. Plus, no need to buy a bunch of kid towels for bath time.
Invest in a Towel Warmer
Totally not a necessity, but certainly a nice to have (even for yourself!) But depending on your house and heating situation, sometimes winter’s can get brutally cold, and the bathroom can be freezing especially when your little one is soaking wet come out of the tub. A towel warmer can make a difference in those frigid months!
A nice toasty warm towel would be pretty nice at a time like that, right?! Just sayin’ ๐
Now you are all set with your baby bath thermometer and can ensure that the temperature is perfectly comfortable for baby, and you both can sit and relax this special time together!
