No one enjoys being covered in milk all day wondering if their baby is okay. 🤍 What's normal and what's not?
Normal spit up usually looks like:
🥛 Small to moderate amounts, and very occasionally big ones
😌 Baby is otherwise content
📈 Normal weight gain
😴 Feeds aren’t dramatic
🧺 Laundry increases, but baby is unbothered
Most babies spit up because their digestive systems are immature. The muscle at the top of the stomach is still learning how to stay closed. They’re coordinating sucking, swallowing, breathing, digesting- all at once.
Milk goes in. Some milk comes back out.
They carry on with their day. That’s the “happy spitter.”
Problematic spit up usually has extra layers.
🚩 Baby seems uncomfortable or in pain
🚩 Frequent coughing, choking, or sputtering
🚩 Back arching and pulling off feeds
🚩 Feeds feel rushed, chaotic, or tense
🚩 Poor weight gain
At that point, it’s worth looking closer.
Sometimes it’s reflux that needs more attention; fast milk flow; latch and swallowing air... lots of things.
Spit up itself isn’t automatically the problem. The context matters.
If your house smells vaguely like sour milk at all times but your baby is thriving, that’s usually developmental and improves with time.
If feeds feel stressful and your baby seems uncomfortable, you’re probably not imagining it.
You don’t have to just accept daily anxiety as the cost of feeding.
Tell me- are we talking “happy spitter” or “this feels like a situation”? 💬
