# Day 109: Everything goes in the mouth

> Grabbing on purpose means anything in reach ends up in the mouth. What's small enough to choke on, the cords and strings to clear, and a sweep of the play area at baby height.

This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Your baby's hands are catching things now, and every catch has the same destination. Today is a look at the room from the floor.

## Heart

Mouthing is how a baby this age studies the world. Early grabs use a mitten-like grip, and most of what they catch goes straight to the mouth; the pincer grasp waits until about 9 months ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx)). Lips and tongue tell your baby more than fingers can yet. It isn't a habit to break; it's a lab, and your job is to stock it safely and clear out the rest.

## Head

The AAP's rule is to remove anything your baby could choke on or get hurt by ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx)). The CDC's version: let them mouth safe things that aren't sharp, hot, or small enough to choke on ([CDC](https://www.cdc.gov/act-early/milestones/4-months.html)). The quieter danger is strangling. Never tie a pacifier to the crib or around your baby's neck or hand ([AAP](https://www.healthychildren.org/English/ages-stages/baby/crying-colic/Pages/Pacifiers-and-Thumb-Sucking.aspx)), and skip amber or other teething necklaces and bracelets: the FDA warned against them in 2018 after reports of choking and a strangulation death ([AAP](https://www.healthychildren.org/English/ages-stages/baby/teething-tooth-care/Pages/Amber-Teething-Necklaces.aspx)). The AAP also says to skip liquid-filled teethers and numbing gels ([AAP](https://www.healthychildren.org/English/ages-stages/baby/teething-tooth-care/Pages/Teething-Pain.aspx)).

## Body

Reach is growing faster than judgment. Babies typically start reaching for things at around 3 months ([AOA](https://www.aoa.org/healthy-eyes/eye-health-for-life/infant-vision)), and by 4 months they often reach for and grasp nearby objects they see ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Babys-Vision-Development.aspx)). Rolling usually starts around 3 to 4 months ([Moon, AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/a-parents-guide-to-safe-sleep.aspx)), so the circle your baby can reach is about to outgrow the blanket. Sweep for the baby you'll have next week.

## Try today

### The choke-size sweep

- **Time:** 10 minutes, with the baby in someone's arms or the crib
- **From the guide:** [Reach-and-grab](https://chorevia.com/learn/3-months#reach-and-grab)

1. Get down on hands and knees in the play area and look at it from your baby's height, under the sofa and the coffee table included.
2. Pick up anything small enough to choke on, sharp, or hot; coins, caps, pen lids, and an older child's toy parts are the usual finds ([CDC](https://www.cdc.gov/act-early/milestones/4-months.html)).
3. Trace every cord and string within a rolling baby's reach: phone chargers, blind cords, bag straps, a pacifier clip. Move them up or out ([AAP](https://www.healthychildren.org/English/ages-stages/baby/crying-colic/Pages/Pacifiers-and-Thumb-Sucking.aspx)).
4. Put three safe things to grab back on the blanket, big ones that won't break, and do the sweep again next week from a little farther out.

**Make it work:** Whatever passes the sweep still gets watched; babies this age don't yet know an edge from a floor, and they won't know a cap from a teether ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx)).

## Watch for

- **Normal:** gagging on a fist shoved in too far, then carrying on; bringing hands to the mouth is a 4-month milestone ([CDC](https://www.cdc.gov/act-early/milestones/4-months.html)). **Call 911** if your baby choked on a small object that could be stuck in the throat, or is struggling to breathe ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Breathing+Trouble)).
- **Normal:** a soaked bib by mid-morning. **Take the bib off before every sleep** ([Shu, AAP](https://www.healthychildren.org/English/ages-stages/baby/teething-tooth-care/Pages/Drooling-and-Your-Baby.aspx)), and **go to the ER now** for any trouble breathing, including ribs pulling in with each breath or wheezing ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Breathing+Trouble)).
- **Normal:** reaching with the hand nearest the toy. **Tell your pediatrician** if your baby struggles to get objects to their mouth, or reaches with only one hand ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Developmental-Milestones-7-Months.aspx)).

## For you

The partner's job tonight is the sweep, and yours is to lie down while it happens. Nap when your baby naps, and go to bed right after the last feed ([Moon, AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/safe-sleep-tips-for-sleep-deprived-parents.aspx)). The play area needs one adult with a clear view, not you specifically.

One line for you. Thoughts about harming yourself or your baby are on the CDC's list of urgent maternal warning signs; seek care immediately, and tell them you were pregnant within the last year ([CDC](https://www.cdc.gov/hearher/maternal-warning-signs/index.html)).

If you're the partner: hands and knees, under the sofa, tonight. Then put three big safe toys back and tell her what you found.
