Reflux in toddlers?

Brianna

My 19 month old will throw up several nights in a row at bedtime, then will be fine for a couple of weeks, then back to throwing up again. It’s always right after he drinks his milk before bed. I don’t think it’s a lactose issue because he’s fine most of the time with it. I just feel like I’m cleaning up puke an abnormal amount. I’m wondering if it’s reflux since it’s when he drinks milk laying down in our arms?

I’ve tried researching online and nothing is making sense. My husband mentioned it at my son’s last doctor appointment, but I don’t think he stressed how often it’s happening and she wasn’t concerned.

I’m thinking of making another appointment. If there is another underlying issue, I don’t want it to be ignored. Has anyone experienced this?
