The new parents had read the instruction manual and were very safety conscious.
"We put it through a hole in the bottom of the portable cot and didn't think about it as a danger...we are first-time parents so we're quite cautious."
Despite the experience, the family kept using the device, she said.

Baby monitor recall after US deaths
One of New Zealand's most popular baby monitors has been recalled overseas after two babies fatally strangled themselves with the device's cords.
New Zealand authorities are investigating Angelcare baby monitors, which measure a baby's movement via a sensor pad placed underneath the crib mattress and are connected to the monitor with a cord.
Two infants died of strangulation in the United States in 2004 and 2011 after pulling the cords loose and tangling them around their necks.
Angelcare Monitors, the firm that makes the popular product, issued a voluntary recall for 600,000 of its monitors in Canada and the US on Friday, and was providing repair kits to secure the cords.
The Ministry of Business, Innovation and Employment is working with the New Zealand distributor, Child's Play, to investigate whether any action needs to be taken here.
A ministry spokeswoman said its Trading Standards division was working with Child's Play to assess the situation. "If it appears a recall is the best course of action then the company undertakes a voluntary recall."
Child's Play owner Dave Austin said he approached authorities to investigate the issue on Friday and was offering a free cord cover to any concerned Angelcare device owners.
"At this stage the recall notice is only relevant to the US," he said. "I've had a lot of customers, between 100 and 115, call and order the cord cover but others have said they don't need it, that they are using their common sense."
The monitor, stocked in most of the country's baby stores, came with clear and simple safety advice.
"There is a set of specific instructions that show you how to install it and have the cot mattress sitting on top of the [sensor pad] and having the cable coming out the bottom so it's not allowed to be grabbed by a child."
Consumer New Zealand yesterday removed the product from a list of recommended baby monitors until a ministry decision was made.
Plunket national child safety adviser Sue Campbell said it was a reminder to parents of dangers that could be hidden in their homes.
"Parents need to be aware of the possibility of strangulation on anything - blind cords, power cords, anything your child can get around [them]."
The US Consumer Product Safety Commission said on its website the device's cord posed a strangulation risk if the child pulled it into the cot. It recalled six models sold between 1999 and 2013 that did not include rigid cord covers.
Strangulation risks
* Secure any low hanging cords in your home. The main risks are blind cords and power cords.
* Be aware of cords on clothing.
