Is there an easy way to supply water? My baby will only drink from the dropper after a few minutes of holding it out in front of him. He will only drink a little of it before he runs off. He has a bowl that he never drinks from (it raises the humidity, so I might take it out). He rarely drinks from his bath. Also, do they absorb water through their vents? I’ve read so many different answers (if you google it, you’ll get both yes and no). Thank you! He’s not badly dehydrated (only a little bit of wrinkled skin, which is occasional), I just want to make sure he gets what he needs!
