At six months, you can gently encourage her behavior, but you shouldn’t expect her to understand and consistently follow “don’t blow raspberries with food in your mouth.” She learns through repeated interactions, and her ability to understand rules and control herself is still developing.

Blowing raspberries is normal at this age. The CDC lists it as a [six-month developmental milestone](https://www.cdc.gov/act-early/milestones/6-months.html). Eating solids gives her new tastes and textures to explore as she discovers what her mouth can do.

I wouldn’t make a big issue of it. During meals:

- Stay calm and keep your reaction low-key so spraying food doesn’t become an entertaining game.
- Pause briefly and give her time to finish what’s in her mouth. Offer the next small spoonful when she’s ready.
- Use the same gentle phrase, such as “Let’s swallow first,” without expecting her to follow it right away.
- Stop offering food if she closes her mouth, turns away, or pushes food away. These are [signs of fullness](https://www.cdc.gov/infant-toddler-nutrition/mealtime/signs-your-child-is-hungry-or-full.html). Blowing raspberries on its own doesn’t necessarily mean she’s finished.

The pause should give her time to eat at her own pace. Don’t use it to punish her or withhold food until she “behaves.” The American Academy of Pediatrics recommends [positive guidance and redirection](https://www.healthychildren.org/English/family-life/family-dynamics/communication-discipline/Pages/Disciplining-Your-Child.aspx) for infants.

For now, a bib and a feeding area that’s easy to wash will probably help more than correcting her. Keep meals calm and pleasant; tidier table manners can come later.
