Consistent high levels can indicate a problem in the home, as well as high indoor levels of spores relative to outdoor levels. Spores of Aspergillus and Penicillium are the same size and shape, so these are often reported as Penicillium/Aspergillus.
The front teeth are the first to erupt at around six to eight months; the back teeth erupt between 18 and 24 months. Teething, sometimes referred to as cutting teeth, occurs until all 20 primary teeth are in place. This is normally around two and a half years of age.
When to Expect Teething to Begin. Most babies' teeth begin to erupt between the ages of 4 to 6 months, though for some it may be earlier or later, Dr. Josen says. And no matter what Grandma says, when your child's first tooth pops in, it has nothing to do with smarts.
