"The perfect part of wearing a carrier is that you get to kiss them," Hassenstaub said before leaning over to kiss 10-month-old Curren on the forehead.
Being able to kiss your baby in a carrier is part of the test to make sure you're wearing it properly.
"You want them to be visible and kissable," said Belle Baby Carriers Owner Julianne Pearce.
Belle Baby Carriers is based in Boulder, with celebrities like Angelina Jolie spotted using the product. Hassenstaub thinks more parents are picking up on the technique, called "babywearing."
"I really do think babywearing is very hip right now," she said.
It comes just in time, because the week of Oct. 10 through 16 is International Babywearing Week.
"Babywearing has been around for centuries," said Pearce, noting the notion that the act of babywearing promotes bonding.
"The heartbeat [of the parent] can be heard, so it's almost like they hear and feel similar sounds to when they were in the womb," she said, adding the result of studies which suggested that babies who are put in baby carriers cry less.
Parents, though, should take safety precautions when choosing a baby carrier.
"Try the carrier without the baby first," suggested Hassenstaub, who is a mother of three. "You can buy a stuffed animal or doll and try it out first before you put a baby in it."
Parents should also read the instructions, register the product with the manufacturer and keep abreast of recall notices. Pearce also notes that the type of carrier a parent chooses should be appropriate for the baby's developmental stage.
"You definitely want a head support for a young child because they don't have good head control until about four months old," she said. "The time to turn a baby around [to face forward in a carrier] is not until they have that strong head and neck control."
Hassenstaub says she'll use a carrier for her baby boy for as long as he'll let her. And that could be a long time.
"I have even worn my 3-year-old when hiking," she said with a smile.
