My almost 4 month old is behaving differently all of a sudden. She was extremely social and vocal, making oohhs and ahhs, razzy noises, even imitating words like hi. For the last week, she's been extremely quiet, smiling less and just not herself. We gave her just a few selective vaccines at the 2 month mark, and she HAS NOT received her 4 month ones. Could this behavior be a normal developmental change? The only other explanation is that she seems to have begun teething. She has all the symptoms. Lastly, I breastfeed and had to be on antibiotics a few weeks ago. Perhaps that triggered something? My sister has a baby exactly one month older than mine, and she said she had noticed a quiet spell in her son. Have any other moms experienced a similar sudden change, and if so, did it resolve itself?
