Frequently asked questions
Should my baby be laughing yet?
Some babies begin laughing during Month 3, while others do so a little later. Both are completely normal.
Is it normal for my baby to put their hands in their mouth?
Yes. This is a normal part of exploration and development at this age.
Why is my baby suddenly more distracted during feeds?
Your baby is becoming more aware of the world around them and may find everything interesting — this is completely normal.
How much tummy time should we do?
Several short sessions each day remain ideal. Many babies become much stronger during Month 3.
Looking ahead
Next month is full of exciting changes. Your baby may begin rolling, laughing more often, reaching intentionally for toys, and showing even more of their growing personality. Many parents find Month 4 to be one of the most fun and interactive stages yet.
