Somewhere around the four-month mark, your baby stares at your toast with an intensity usually reserved for religious experiences, and everyone in a five-metre radius says some version of looks like someone's ready for solids.
Reaching for food and watching you eat are actually not the readiness signs most professionals look for. Here's what genuinely matters.
The three signs that actually count
- Sitting with minimal support and holding their head steady and upright
- Losing the tongue-thrust reflex - the automatic push that shoves anything but liquid back out of their mouth
- Showing real interest in food itself, not just in you - opening their mouth, leaning forward, trying to grab
Why age alone is not the marker
Current guidance points to around 6 months as the general starting window, with the emphasis on 'around' doing a lot of work. Some babies show every readiness sign at 5.5 months; others aren't there until closer to 6.5. Both are within normal range.
Starting significantly before these signs are present isn't about willpower or a baby being advanced - a baby who can't yet sit stably or has an active tongue-thrust reflex simply isn't physically set up to manage food safely yet, regardless of how interested they look.
What the first weeks are actually for
In the early stages, solids are about exploration and practice, not nutrition - breastmilk or formula is still doing the heavy lifting for a while yet. That reframe takes a lot of pressure off a first attempt that ends in more food on the floor than in the baby.
Iron-rich first foods are worth prioritising once you do start, since a baby's iron stores from birth begin to deplete around this age - well-cooked meat, iron-fortified cereal, or legumes are common starting points, alongside whatever approach (purees, baby-led weaning, or a mix) suits your family.
A few things that trip people up
- A baby waking more at night around this age is not on its own a sign they need solids - sleep and hunger cues get conflated more than they should
- Gagging is a normal, noisy safety reflex and looks far more alarming than actual choking - it's worth knowing the difference before you start
- There's no need to introduce foods in a strict rotation or order - allergen introduction guidance has moved toward earlier, not later, introduction of common allergens
The honest version
There is no prize for starting early, and no harm in a few extra weeks if the signs aren't quite there yet. The signs exist precisely so you don't have to guess.
When they do line up, it's messy and slow and mostly beside the point for a while - and that's exactly how it's supposed to go.
