Let's say that you have regulated humidity to the optimal level. Nevertheless, the baby with his heavy breathing and cry is still hinting that the problem didn't disappear. It means that it is time to pay attention to the other indicators:
- Frequency of dust formation on every surface in the house, especially on the floor
- Degree of windows fogging
- Indoor smell — is it dampness am I feeling?
If even with regular cleaning there is a thin layer of dust still appears on the floor, windows fogging more than 3-5 cm from the edge, and you feel the smell of dampness, it means that the problem is uniquely in ventilation. It wouldn't be excess to notice again how dust and newborn babies are not compatible.
