[EX Q]: Pauline Hilborn   a mom of two in New York City  describes  herself  as an expert on meltdowns based on the experiences of  her  daughter  who  she  says is "7-years-old but sounds more like 13."
Case in point:  Hilborn's daughter  wanted a ponytail like the pop singer Ariana Grande  but felt like  her  mom didn't do the ponytail properly and put it in the wrong place.
" She  came out crying and said  'Ariana Grande's ponytail is here not here '" said  Hilborn   pointing to the place on  her  head where  her  daughter preferred the ponytail to go  not where it ended up.
 Pauline Hilborn  and  her  kids  ages 4 and 7.
"I was at a loss for words "  she  said. "I had no idea what to say but my husband said  'Well   she 's right you know ' which didn't help the situation."
Debi  another mother of two in Manhattan  says her 7-year-old has definitely had some tantrums. When I asked  her  son what a meltdown is  he told me it's when you cry a lot. When I asked him to imitate one  he said he keeps screaming until his mom lets him have whatever it is that he wants at that moment.
