Spitting up

# I hear you — that worry is so real, and you're not alone in it. --- ## ① Your feeling matters first That moment after every feed — watching milk come back up, wondering if something is wrong, feeling helpless — that's genuinely unsettling. You're a thoughtful parent noticing patterns and caring deeply about getting it right. That instinct to check in is good. Let's work through this together. --- ## ② What's actually happening with your 1-month-old At one month old, babies have tiny stomachs (roughly the size of a large egg — about 80–120ml). Spit-up after feeds is **extremely common at this age** and usually doesn't mean there's a problem. Here's why it happens so often: - **Immature valve**: The muscle between her food pipe and stomach (the lower esophageal sphincter) is still developing. It's not tight yet, so milk comes back up easily. - **Overfeeding by even a little**: Even 10–20ml too much can trigger spit-up. - **Air bubbles**: If she swallows air while feeding, the burp brings milk with it. - **Position after feeding**: Lying flat right after eating makes it easier for milk to come back up. **This is developmental — not dangerous — at her age.** --- ## ③ How to tell if it's normal spit-up vs. something to mention to a doctor **Normal spit-up** (what most 1-month-olds do): - Small amounts (a tablespoon or two) - Baby seems comfortable and happy after - She's gaining weight steadily - No green or blood-tinged vomit **Worth mentioning to your 소아과 doctor**: - She seems in pain or distressed after spitting up - She's losing weight or not gaining - Spit-up is forceful (shoots across the room) - She refuses feeds or seems uncomfortable during feeding - Vomit looks green or has blood in it --- ## ④ Three things you can do starting today **1. Paced bottle feeding (if you're formula feeding)** - Hold her at a 45-degree angle — never flat - Let *her* latch onto the teat; don't push it in - Pause every 20–30ml by tilting the bottle horizontal - This gives her brain time to register fullness and prevents overfeeding **2. Keep her upright for 20–30 minutes after feeds** - Hold her upright against your chest, or - Lay her on her side in her bassinet (supervised) - This helps gravity keep the milk down **3. Burp gently but don't obsess** - One good burp during a feed (halfway through) and one after is usually enough - If nothing comes up after 30 seconds, she's fine — move on --- ## A thought to hold onto The fact that she's 1 month old and you're already noticing patterns and asking questions means you're paying attention. Most newborns spit up, and most grow up just fine. **If her weight is steady and she's content most of the time, this is almost certainly normal baby behavior, not a problem.** --- ## **Next step** At your next 예방접종 (vaccination visit) or routine check-up at the 소아과, mention the spit-up to your doctor. Bring your phone with a note of roughly **how much** she typically spits up (a teaspoon? a tablespoon?) and **whether she seems uncomfortable**. That information will help them reassure you or spot anything that actually needs attention. **Do you have a 소아과 doctor you can reach out to by phone if you're worried before the next visit?** Many clinics have advice lines for new parents.
