Help!! Spit up? Throw up? Concerned 😧

So my 5.5m old has been drooling a lot lately. We definitely think a tooth is breaking thru soon. But the last two days he’s been either biting, pulling or refusing the bottle more.. we notice that he seems to want to play with it more.

Yesterday morning he drank his bottle and seconds later everything came up, but still managed to keep the rest of his 32oz down and his oatmeal that he is getting introduced to. Today he seemed fine woke up to feed at 5:30am then slept till 9:30 had his oatmeal and 8 oz of bottle and went back down around noonish for a nap. Woke up 45 mins later but seemed to be fine he played a while then dad fed him around 3ish 6 oz but noticed the playing with the bottle while trying to get him down to nap.

He then went to make more cause he thought he wanted more milk and noticed that it all came up again..

Anyone going thru this or have advice. First time mommy and very scared with everything going on especially since I am still working and everything going on.
