Babies hands and feet are not a good indicator of their body temperature as babies do not have a fully developed circulatory system so extremities such as hands and feet can feel very cold and the baby is actually warm.
The easiest way to check is to feel the back of their neck. If it is damp (sweating) then they are too hot and you should adjust accordingly.
I find that an accurate room thermometer is invaluable. The room a baby sleeps in should ideally be between 16 and 20 degrees.
For 16-18 temperatures a vest, sleepsuit and 2.5 tog sleeping bag should be plenty. 18-19 degrees sleepsuit and 2.5 tog sleeping bag. 20 - 21 degrees sleepsuit and 1 tog sleeping bag. 22 - 24 short sleeved sleepsuit or vest and a light sheet. 25 plus vest only.
If you want to use tog values then remember to include the tog value of the nappy (increases when wet). I have the tog value list somewhere in DDs paperwork I will see if I can find it and post the values on here.
When we left hospital with dd we were given an NHS book that had information about tog values in it. I can't remember all of it but basically each layer you put on your child has a tog value e.g. I think a vest was worth 1 tog, a babygro was worth 2. You were then given a total value of togs depending on the temperature of the room the baby will be in and you dress your child accordingly. I can't find the book and the closet thing I could find on the Internet after a quick search was this
I can also remember being told don't check your baby's temperature by feeling hands or feet as this can make you think they are cold when really they aren't. Just stick your fingers down the top of their vest to feel their chest and if that's nice and warm then they're ok.
Our dd was born in a very cold winter and I became obsessed with room temp and tog values and can't believe that I've forgotten it all now! .
Do you put these on your baby over a vest and their normal sleepsuit? Or just over a vest?
I put one over a vest on my 7mo dd last night then put her in her sleeping bag but her hands were still cold this morning, paranoid that I'm gonna overheat her if I put her normal sleepsuit on her aswell!!
