Early Signs of Emotional & Behavioural Difficulties at 9–12 Months

At nine to twelve months, your baby is just learning how to feel safe, soothe and connect — so what's normal, and what's worth a gentle second look?

In short

At this age there is no diagnosis of "emotional and behavioural difficulties" — a baby's emotions are still being built through your care and connection. What matters is the pattern of relating: most babies this age seek comfort from familiar people, settle with soothing, share smiles and show interest in faces and play. Signs worth observing — never diagnosing at home — are persistent inconsolability, very little eye contact or social smiling, or a baby who seems hard to comfort and rarely seeks you out. These are reasons for a reassuring developmental check, not alarm.

What is typical — and what's worth watching

Usually emerging by 9–12 months (reassuring):

• Smiles and laughs, enjoys peek-a-boo and back-and-forth play
• Looks to you when unsure (social referencing), reaches to be picked up
• Shows stranger wariness or separation upset — a sign of healthy attachment
• Can be soothed and settles after crying with familiar comfort

Worth gently observing and mentioning at a check:

• Persistent, hard-to-soothe crying or distress that rarely settles with comfort
• Very little eye contact, social smiling or shared enjoyment over several weeks
• Seeming "flat" — rarely showing pleasure, interest or upset
• Not seeking closeness or comfort from familiar carers, or extreme distress with everyday handling
• Major, lasting changes in feeding or sleep that aren't explained by illness or teething

Remember: tiredness, teething, illness, a new routine or a hard few days can all unsettle a baby briefly. What matters is whether a pattern persists over weeks and affects feeding, sleep and connection.

When to seek a check

Because emotional wellbeing at this age lives inside the parent–baby relationship, the right step is not a behaviour label but a warm developmental and wellbeing review — for your baby and for you. Speak to your paediatrician promptly if your baby is very difficult to console most of the time, shows little social connection over several weeks, or if you yourself are feeling low, anxious or overwhelmed, as parental wellbeing strongly shapes a baby's emotional world. A general developmental screen is the right starting point.
