Attachment Difficulties
Worrying about Attachment Difficulties at 3–6 months
At 3 to 6 months it is too early to identify Attachment Difficulties — this is never diagnosed in early infancy. What matters now is enjoying responsive, warm care and watching the everyday building blocks of connection: social smiling, eye contact, calming to your voice, and cooing turn-taking. If your baby consistently doesn't smile, make eye contact or settle, see a clinician for a general developmental check, not an attachment label. Only a Pinnacle clinician can assess.
If you're watching your 3-to-6-month-old and wondering whether something in your bond is amiss, take a breath — this is a tender, loving question, and there's a reassuring answer.
In short
At 3 to 6 months, it is far too early to identify Attachment Difficulties (ICD-11 6B44) — this is not a diagnosis made in early infancy, and there is nothing for you to "worry" about as a label at this age. What matters now is simply that you and your baby are building the back-and-forth of warm, responsive care. Babies at this age are meant to be settling into connection, not displaying a disorder. The right step is not a worry list but gentle observation of your baby's everyday social cues — and a routine developmental check if anything feels off.What is appropriate to notice at 3–6 months
Rather than "signs of a condition", these are the everyday building blocks of healthy early connection you can gently enjoy watching for:- Social smiling — smiling back when you smile, usually well established by around 3 months
- Eye contact and gaze — looking at your face, following you with their eyes
- Calming to your voice and touch — settling when you hold or soothe them
- Cooing and "conversational" babble — taking turns with sounds when you talk to them
- Brightening when you appear — showing pleasure at familiar faces by 4–6 months
These emerge on a wide, normal range, and an off-day, illness, tiredness or a quieter temperament are all perfectly ordinary. Attachment is built through countless small, repeated moments of comfort — not perfected in a single interaction. None of this is your parenting being judged; responsive care is something that grows over months.
When a check becomes meaningful
Bring it to a clinician if, consistently over time, your baby does not smile socially, rarely makes eye contact, seems hard to comfort no matter who holds them, is unusually "floppy" or stiff, or has lost a skill they once had. These point towards a general developmental and feeding/health review, not an attachment label. A formal look at attachment patterns becomes meaningful much later in early childhood, once a child's relationships and behaviour can be observed across settings.The Pinnacle way

What to watch
Enjoy the building blocks of connection: social smiling by ~3 months, eye contact, calming to your voice and touch, and cooing turn-taking. Seek a routine developmental check — not an attachment label — only if, consistently over time, your baby does not smile socially, rarely makes eye contact, is very hard to comfort regardless of who holds them, seems unusually floppy or stiff, or loses a skill.
Try this at home
Build tiny, predictable moments of connection — talk softly during nappy changes, smile and wait for your baby to smile back, cuddle when they fuss. These repeated, ordinary moments are exactly how a secure bond grows.

Frequently asked
Can my 3-to-6-month-old be diagnosed with Attachment Difficulties?
No. Attachment Difficulties (ICD-11 6B44) is not diagnosed in early infancy. At this age, attachment is still being built through everyday responsive care, and a formal look at attachment patterns becomes meaningful much later in early childhood. Any assessment is done only by a qualified clinician.
What should my baby be doing socially at 3–6 months?
On a wide normal range: smiling back when you smile (usually by around 3 months), looking at your face and following you with their eyes, calming to your voice and touch, cooing and taking turns with sounds, and brightening at familiar faces by 4–6 months.
When should I actually see someone?
Book a general developmental check if, consistently over time, your baby doesn't smile socially, rarely makes eye contact, is very hard to comfort no matter who holds them, seems unusually floppy or stiff, or loses a skill they once had. This points to a routine developmental review, not an attachment label.
Does this mean I've done something wrong as a parent?
Not at all. Attachment grows through countless small, repeated moments of comfort over months — not from one perfect interaction. Asking the question itself shows the attentive, loving care that builds a secure bond.
