Babies often sleep with their hands above their heads in the womb, so they continue to behave this way after birth. Since it is a habit, we must find a way to correct the child. You can use a small quilt to wrap him a little tighter, so his hands are relatively difficult to take out, and slowly he gets used to being inside the quilt, so that the problem will not occur again. During the day if he does not like to wrap, we are artificially corrected, when he appears to take his hand out, it is timely to give him wrapped in, get used to it will be natural. If you really can’t correct, this is not a big problem, no need to give the child special treatment, is a sleeping behavior habits will not affect his growth and development, if the child is afraid of cold to, we can make the home environment temperature a little higher, such as in 22 ~ 23 degrees, so that even the child’s hand outside will not appear to be cold. If this form continues, this will not affect his growth and development, as long as it does not get cold, there is no big problem. If the hands and feet are cold, you can take the way of rubbing the heart of the hands and feet or bring him a small glove, are able to keep him warm.
