In the past, every time she cradled her newborn baby girl in a sling, yoga teacher Juliana Phua felt a strain on her shoulder.
"I could not walk properly as I had to keep one hand on her all the time," she says.
It was only when she stumbled on a Facebook page called Babywearing Singapore early last year that she realised she was wearing her baby wrongly.
The 34-year-old recalls: "She was hanging too low and the weight was all on my shoulders. Also, I had put her in cradle, a position which I learnt can be dangerous because it causes her chin to press against her chest and this can block her airway."
Since then, she has been carrying her daughter, now 16 months, the right way - in an upright position, with the child's knees higher than the bum so that her spine is in its natural C shape.
Ms Phua is now so comfortable baby-wearing that she even teaches and practises yoga while doing so.
Baby-wearing is the practice of wearing the baby on a sling or other baby-wearing gear.
It is said to produce happier and calmer babies, among other things. Together with co-sleeping and breastfeeding, it is a major tenet of attachment parenting, a style of child-rearing made popular in the United States by paediatrician William Sears.
In recent years, there were a few deaths related to the use of slings in Britain, the United States and Canada, prompting the US Consumer Product Safety Commission to advise caution when using slings for babies younger than four months. The deaths were mostly due to suffocation.
About 10 mums started Babywearing Singapore in late 2013 to promote safe and comfortable baby- wearing, after realising that many parents were wearing their babies wrongly. It has more than 6,400 members.
There are at least five baby-wearing mothers here who have undergone training by certified trainers from baby-wearing schools in Britain, Australia and Germany.
One of them, Ms Nur Afifah Mokhtiaruddin, 27, who runs an online business selling custom-made ring slings, says: "Wearing a carrier is not just a matter of following instructions on a piece of paper. Some babies may have certain habits and parents need more specific instructions on how to carry them."
For instance, certain babies like to arch their back and parents need to learn to wrap them in such a way that they will not slip out easily.
Also, while soft structured carriers, which usually come with belts and buckles, are generally easier to use, non-structured carriers such as wraps and ring slings have a steep learning curve and may require more guidance.
Baby-wearing advocates advise parents to buy carriers of a good quality because cheaper designs may have buckles that break more easily.
A good sling costs from $60 to $80, a soft structured carrier from $90 to $150 and a wrap $90 and above. A sling is usually worn over one shoulder whereas a wrap is more versatile and can be worn on one or both shoulders.
To allow parents to try the different types of carriers before they commit to a suitable one for themselves, Babywearing Singapore started an online sling library in January. Parents can rent carriers for two weeks for $10.
Ms Afifah says some parents give up baby-wearing when their baby outgrows the carrier, but there are "toddler worthy" and even "preschooler worthy" carriers, which are usually made of tougher materials.
Dr Rajeev Ramachandran, a consultant at the division of General Ambulatory Paediatrics and Adolescent Medicine from the National University Hospital, says baby-wearing is safe so long as it does not cause discomfort or injuries to the baby.
He says injuries related to baby-wearing are generally very rare here as parents are very careful with it.
Dr May Lim, an assistant professor from the Singapore Institute of Technology and a trained occupational therapist, says baby-wearing can be calm and soothing. But parents should ensure that they wear their sling correctly, even when they are in a hurry. Otherwise, it can strain their shoulders and backs.
Parents here say they are careful to ensure that they carry their baby safely in the right carrier.
Ms Debbie Wee, 28, a regional campaign services manager, and her husband, a 35-year-old marine surveyor, follow the "Ticks" rules of safe baby-wearing from the UK Sling Consortium (see below).
Ms Wee says: "We want to enjoy the benefits of baby-wearing, but in a way that is safe and comfortable for both the baby and ourselves."
She tried at least three types of carriers before deciding on a woven wrap. Her husband had a soft structured carrier custom-made for him from an overseas manufacturer as he could not find one that fits him here.
