help, baby swallowed water

So we were giving a bath to our daughter (almost 14 months old). We have a little bottle that you can fill with water and when you squeeze it, water sprouts from the top. (it almost reminds me of the bottle they give you after you deliver and your all sore down there so they want you to wash off after the bathroom... Anyway...)my husband was filling it and she took it from him and put it up to her mouth and squeezed it, except there was no top of it so a huge amount of water went into her mouth, she instantly started coughing and even threw up. She coughed a few more times and then went back to acting like her normal self, splashing and all. I'm nervous about dry drowning but also don't want to be a crazy mom by freaking out. Any suggestions?
