Water in the lungs?

So today my husband was bathing our 8 week old baby and while he was pouring water on baby’s head our LO made a sound as if he swallowed me/inhaled some water. He started crying but soon after he stopped and has been asleep since (this was like 30min ago). Do you think I should take him to the doctor? Could it be possible that water went into his lungs and something fatal can happen??

My husband didnt saw water on his face but we think maybe some drops got to his face and thats what got inside, we’re sure it wasnt a big amount of water.

Im a little bit worried😔
