She had been reported missing about 3:30 a.m. She was last seen by her family asleep in her crib around 9:30 p.m. Thursday.
It was a tense few hours Friday morning, but a little girl that went missing was found safe in a nearby apartment nearly 6 hours later.
Authorities were having the child, who was only wearing a pink one-piece sleeper, checked out at a hospital.
According to the Manchester Information Facebook site, several K-9 units were searching the area on the ground while the New Hampshire State Police air wing was using its thermal imaging camera while searching from the air.
Police did an extensive search of the home and the surrounding neighborhood.
Pena said her daughter's condition is "good".
Police said they appreciate offers from people to help in the search, but right now they want everyone to stay away, so officers can do their job.
Temperatures were below freezing when the child was reported missing. "I want to thank them so much", Geraldine Pena, the girl's mother, said.
