Serena Curtis, 31, had been enjoying a girly night in with pal Jade Dickerson when the bizarre accident unfolded.  While the kids were being looked after, the pair polished off two bottles of wine.

Mother-of-three Serena then decided to sit in her boy’s highchair...and wedged herself into the seat. 

She and Jade, 27, struggled for an hour to get her out — with Serena even stopping for a heater.
Eventually the giggling pals had to call the fire department, who freed her.
