Your 24-week-old baby: what to expect
This is roughly day 162 to 168 since birth (about 5.5 months). Your baby is 8 weeks into the "grabbing everything" window, which research and CDC milestones cover across weeks 17 to 26. Prefer the bigger picture? See month 6 at a glance.

The short answer
A fussy cluster was described around week 17. Expect everything to head for the mouth: that's how babies explore now, per the CDC's own milestone list. Rolling can start changing sleep positions, and turn-taking "conversations" of sounds begin.
Babies this age often laugh at the mirror. Self-recognition is years away; the entertainment is immediate.

Most babies do these by 6 months (CDC)
Social & emotional: Knows familiar people · likes looking in the mirror · laughs.
Language & communication: Takes turns making sounds with you · blows raspberries · makes squealing noises.
Movement & thinking: Puts things in mouth to explore · reaches to grab a toy · closes lips to show they don't want more food · rolls from tummy to back · pushes up with straight arms on tummy · leans on hands to sit.
What can help this week
Mouthing everything is exploration, not a habit to break: keep reachable areas clear of small or unsafe objects instead of fighting it. Offer toys with different textures and shapes. Once rolling starts, never leave your baby unattended on a changing table, sofa, or bed, even for a second.
How to respond this week
Meet the grabbing and mouthing halfway: hand over safe things to explore instead of saying no all day, and name what they reach for. When they fuss, a change of scene or a new texture often resets the mood faster than a cuddle alone.
And you: You will be repeating yourself and picking things up off the floor a lot. That is the job right now, not a sign you are failing. Small breaks still count.
Talk with your pediatrician if…
Your baby is missing one or more of the milestones above by 6 months, or has lost skills they once had. That is the CDC's own advice: don't wait, talk with the doctor and ask about developmental screening. And if you're simply worried, that's reason enough to call.
In about 2 weeks, your baby moves into "on the move" (weeks 26 to 39).
