You've blinked, and now you are halfway through your baby's first year. Hitting the 6-month mark is a big deal, and you might notice some exciting changes in your little one from now on. From sitting with support to starting solids (say hello to messy mealtimes), this stage is about exploring and navigating the wonders of this whole new world for you and your not-so-little baby.
You may notice that your child is quickly hitting their baby development milestones; it’s such an exciting stage. But it is completely normal if your baby is reaching milestones at their own pace. So don't worry if your little one isn't quite there yet. All babies develop differently, and this guide is backed by expert insight from Consultant Paediatrician Dr José Costa and midwife Susan Hogan to help you know what’s typical and when to reach out for help.
If you’re a first-time parent or caregiver, think of this as a gentle go-to guide to help you feel more confident as you navigate this exciting (and sometimes overwhelming) stage.
6-month-old baby development milestones:
Sleep Patterns and routine for your 6-month-old baby
Your six-month-old should now sleep about 15 hours daily (although it might not always feel like it). At six months, babies can reach six to eight hours without waking for a feed.
"Your baby may still be waking every two hours, or they may be sleeping for longer stretches at night, possibly up to eight or nine hours," says co-founder of The Baby Academy, Susan Hogan.
"They may also take two to three naps during the day, each lasting about 45 minutes to three hours. With sleep, it's important to remember that there are many variations of 'normal'"
To give you a guide, here is our sleep schedule recommendation.
• Cognitive development - Dr Costa says that most babies will also start to laugh between six and seven months.
"As your baby’s hand skills improve, they will also start exploring objects more, moving them from hand to hand and briefly searching for a fallen object." He adds.
"Your six-month-old may start to make more sounds and possibly say their first word, eg, DaDa! But they will not yet be able to have a conversation. They will still be learning to communicate through facial expressions and body language," adds Susan.
• Physical development - "Your baby’s growth will start slowing down, and soon they will be able to sit unsupported. This will allow them to look around them, trying to reach objects nearby," explains Dr Costa.
"They may also start to develop more control over their hand movements and be able to transfer objects from one hand to the other," says Susan. "You might hear other parents saying that their baby is left-handed or right-handed, but it is worth noting that at this age of your baby’s life, it is not normal for them to have a hand preference (hand preference usually starts to develop between the ages of two to four years old)."
"At six months old, your baby will likely drink about 700 ml (about 24 ounces) of breast milk or formula daily. They may also start to eat solid foods at 6 months, but breast milk or formula should still be their main source of nutrition," says Susan.
As your baby begins weaning, Dr Costa advises that parents should follow a schedule when it comes to mealtimes. "Parents should aim to feed their baby two to three meals, with daily solids. In total, they should have six meals, with the remaining being either bottle or breast, often the first and last meal of the day."
6-month-old baby growth
Your baby will likely weigh about 7 kg- 9 kg (about 16-20 pounds) and be about 65 cm (about 26 inches) long. "Of course, every baby is different and will grow at their own rate," reminds Susan. "You will be assigned a Health Visitor (HV) who will be your link to healthcare professionals. Your HV will ensure your baby is thriving in the first few days. weeks, and months of their life."
6-month-old baby health
• Teething - You can expect your baby's lower central incisors - that's her two front bottom teeth - to emerge at around six months. Common teething symptoms include dribbling, chewing, red gums and cheeks and irritability. Thankfully, there are plenty of teething remedies to help your little one.
• Sterilising - While you might wonder if you can stop sterilising bottles at 6 months, the NHS advises that this must be continued until your little one is at least 12 months old.
Things to think about at 6 months
• Play - There are plenty of fun activities for 6-month-old babies that you can do from home that will aid their development and help enhance your bond even more.
"Encourage your baby to explore their environment and play with toys to help with their development," Susan suggests.
You can increase the length and complexity of your sentences and start playing small games with them, including peek-a-boo, " suggests Dr Costa. Using mirror toys will help them recognise themselves and control their movements, " he adds.
• Weaning - NHS advice states that weaning should start around six months of age, and if your little one can sit up holding their head and chest straight and steady, now is the time to consider whether you are interested in baby-led weaning or spoon-fed weaning.
"Always offer your baby a variety of healthy foods and try to include foods from different food groups to ensure that they are getting all of the nutrients they need," Susan recommends.
Introduce a cup or beaker - Introduce your baby to an open or free-flow cup without a valve, as this is better for your child's teeth and will help them learn to sip. It may get a bit messy at times, but patience is key.
Sitting up - After learning to roll around at five months old, it's likely that your youngster will have full control of their neck muscles now, which means they might be trying to sit up unassisted between now and seven months. This may only last for a few seconds, but it's all good practice. Surround them with pillows just in case they topple.
