At what age will your baby reach each developmental milestone, and what different events will take place each month? It’s one of the key things most parents are keen to know.

Baby development milestonesI was no different; a typical new mum, I spent a lot of time searching websites for more and more information, consulting with the health visitor at baby clinic, and ringing my mum to ask endless questions along the lines of ‘when will the baby roll over?’ and ‘should she have more teeth yet? She would often reassure me that babies move at their own pace and everyone catches up eventually, which is very true. Here’s our guide to baby milestones, and the average age at which babies will reach each developmental step - remember these are average ages though, and lots of babies will do these things later or earlier: You should start to see proper smiles from your baby between 4-6 weeks. However, like most parents you’ll probably be convinced that you’ve seen their first smile sooner (ignore everyone who tells you that it’s just wind!) Some babies can flip themselves from front to back from as early as three months, and often with no warning, so watch out if you’re changing them on a high table. Most babies start to sit up between 6-8 months. The current guidelines for starting your baby on solid food state to wait until they are six months old. If you’re confused about baby-led weaning vs the puree approach, read Fran’s guide to weaning and April’s blog posts focusing on baby feeding, including top weaning tips from all the bloggers. Again, all babies are different, but most start teething from around six months. They should start crawling from 6-9 months. Make sure your house is baby-proof - nothing will be safe! Babies tend to start to walk between 10-18 months. Before taking solo steps they will pull themselves to stand, cruise around the furniture and practise taking steps with a pram or walker toy first. From 12-18 months your child should start to take an interest in words, respond to their own name and start to speak (‘dada’ is usually the first word for most children, it was for mine!). From 1.5-2 they will know a string of words and start to string simple sentences together.

Remember that this is only a guide, and all babies can be very different. If you’re concerned about anything, it’s better to speak to a health visitor or doctor first, rather than consulting Dr Google.
