Strong and secure attachment is vital to your baby’s development. You can build attachment by learning to read your baby’s signals and knowing how to best respond to your baby’s needs.

Some parents worry that controlled comforting will hurt attachment, but research shows that when this settling strategy is used appropriately, there’s no evidence it harms babies or attachment.
Attachment is the strong, long lasting bond between a baby and his caregiver.
Secure attachment develops in response to consistent and sensitive love and care in the first months of your baby’s life. It gives your child an important start to healthy social, emotional and cognitive development, building the foundation for a sense of security, safety and good coping skills.
Babies attach to significant grown-ups in their lives. This is most often their parents but can also include other people who regularly care for them, such as grandparents and paid carers. Children can, and will, attach to more than one person.
Attachment to other people doesn’t affect your baby’s attachment to you – it helps her learn about being close to people.
Babies who experience care that is unresponsive, unpredictable or threatening can develop attachment problems that slow their development.
Babies and toddlers try to get comfort and protection from the people they’re attached to. Babies have different attachment behaviour to show different needs.
To show they need attention, for example, young babies might:
To show when they need a break or perhaps a different, gentler approach, young babies might:
It’s important to respond to attachment behaviour in a way that meets your baby’s needs.
When your baby gets what she needs, like a smile, a touch or a quick cuddle, she feels safe. She knows she can relax, play, explore and learn again. In this way, attachment provides the base for healthy development.
When attachment behaviour isn’t followed by reassurance, babies can sometimes respond by feeling afraid and clinging even more. As an example, this could happen if a parent encourages a toddler to be ‘brave’ and independent before he’s ready.
The following tips can help you use attachment to ground your baby’s growth and development.
By about six months, babies have usually developed important attachments, but might fear grown-ups they don’t know very well. This is a natural part of learning to feel safe in the world, and they’ll soon adapt to these new people too. Try to make sure you’re around for reassurance.
At this age, it’s also common for babies to cry and experience separation anxiety when you leave them with someone else.
Over the next few years, babies and toddlers will gradually learn to manage longer separations from their special people. At first they’ll like to check that you’re around – they might even follow you into the toilet! But this is all part of building confidence.
By age three or four, children can usually manage a half-day or so with unfamiliar people (outside their circle of carers), without being upset. But some children take longer. It depends on their temperament and early experiences.
Separation and sleep
Babies who have slept well for their first six months or so might start to wake at night, or might not want to go to sleep. They could be experiencing separation anxiety, so you might want to read more about promoting independent sleep in babies over six months.
