ceeveebee Sat 09-Jun-12 21:59:17. One of my NCT group's baby has a condition caled 'wry neck' although that's not the technical name for it! His head lolls to one side and he can't hold it upright very well. She took him to GP a few times before going private and getting a diagnosis. He is having physio twice a week to correct this.

They start to throw things. They pull up to stand, they stand holding onto furniture, and they can walk when led. By the time they are 12 months old, most babies can weigh three times what they weighed at birth and gain about an inch per month in length. The average infant at one year may be between 26–30 inches long.

Definitely encourage parents to get it checked out. My DS1 was craling by 9 months and walking at 10 months, DS2 is just 5 months and holds his head up perfectly and sits up well too so it doesn't sound like 'normal' development to me but then there are huge differences in how babies develop and when they do certain things.

1 to 2 Months. After the completion of first month, the baby briefly tries to lift his head and turns it side to side during tummy time. It is also observed that coordinated and strong babies (at the age of 6 to 8 weeks) can also raise their head up during tummy time. While being carried on the shoulder, they try to hold and control the shakiness of head but this is not for long time. The babies will also try to hold their heads while sitting in front pack and car seat.

Most of the babies do not require much head support at or around 4 months of age. At this time, the baby will likely to raise the head while lying on back and may try to prop up on elbows during tummy time just like a mini cobra. By the end of baby’s six month the head control and neck muscles are fairly strong.

Dp and I looked after dp's nephew today and I've noticed that he can't hold his head up properly. Also, if you sit him up, he falls to the left. His head lolls to the left too, and he canstantly shakes his head too. Is it anything to be concerned about do you think?

Knowing when do babies hold their head up is not enough, it helps to know how baby's head control develops so that you can do the right thing to encourage him/her to hold up his/her head.

However, she was also very strong and could hold her head up by the 12w check up and sit up by herself by the 16w checkup. Torticollis involved muscles on one side being tighter/shorter than the other side so DD couldn't physically turn her head to the right; in this case it sounds like the baby's floppier than normal?

Two infants born at the same time may be very different. Some infants are very quiet and sleep a lot. Other infants are very active. Accepting these differences will make it easier to take care of infants and help them grow and develop. A child that walks or talks at a younger age than another child is not necessarily better or more advanced. This guide will share characteristics of most infants.
