We were at the beach today and Maggie wouldn't drink from her sippy cup (typical 18 month old!). So I gave her some water from a water bottle and after a few sips she got wide eyed and started coughing. She coughed for about 1 minute and then seemed fine. We came home about 3 hours later and she coughed a few more times. She is acting fine, but should I worry about water in her lungs and the possibility of pneumonia? She NEVER coughs otherwise so it is kinda freakin' me out. Thanks.
