Is it OK to take a two-month-old baby out in fresh air and cool weather (14 C, 57 F) if properly warmed by adequate clothing? How long can the baby be outside?
There is no inherent risk for even a newborn just from being outside, compared to being in a building, so yes, it is ok. As a matter of fact, exposing a small child to diverse environments (within reason) probably stimulates a healthy development.
That said, if there are specific risks associated with being outside, you should be aware of them and take appropriate precautions. Possible risks that come to mind are:
- exposure to cold (make sure the child is adequately clothed)
- overheating (same)
- sunstroke (same again, plus keep the child in the shade)
- very loud noises
- things that scare the child (depends on child)
- danger from motor traffic
- danger from animals (pet dogs or wild animals)
If you take precautions as necessary for your specific environments, I don't think there's anything to worry about.
As a parent, remember that your wellbeing is also important. Not important enough to endanger your child, of course, but if a breath of fresh air helps you feel good, by all means take your child outside.
