Just 24 days

Things have changed since my first child was born in 1961. The thought then was that they needed some time to build up immunity before meeting the world and its bacteria, viruses and contaminants. When I was on my way out of the coffee shop this morning I stopped at a table and asked, "How old is your little one?" "Three and a half weeks," she said. So I looked it up at several web sites thinking perhaps there was new advice. Doesn't seem to be.

"During the next several months, the antibodies passed from the mother to the infant steadily decrease. When healthy babies are about two to three months old, the immune system will start producing its own antibodies. During this time, the baby will experience the body's natural low point of antibodies in the bloodstream. This is because the maternal antibodies have decreased, and young children, who are making antibodies for the first time, produce them at a much slower rate than adults. Once healthy babies reach six months of age, their antibodies are produced at a normal rate."
