Water?

Nikole
My 7.5 old today saw me drinking water out of a cup whioe she was on my lap and she grabbed the cup ajd put to her mouth, so i gave her a drink. She immediately wanted more. After like 5 drinks i took it away although it seemed she wanted more. I heard they can het seizures with too much water? Is that true should i have stopped her? She is fornula fed, she already ate. She maybe its solids once a day. I just thought it was interested. Not just her drinking from a cup but wanting water espesially ive tried ro give a tiny bit in the bottle with no interest before.
