When did you baby sit unassisted?

Hi there,

I know all babies are different but just want to know when your babies were able to sit up unassisted?

My son is 7.5 months and still can't sit up unassisted.. I'm starting to feel a little concerned about it as it seems most babies can do this by 6 months.. But wondered if anyone else had a 'late bloomer' compared to the average age and when it happened?

Also is there anything I can do to hell him? I'm making him sit up on the floor with a toy in front of him to lean towards and play with a few times a day as 'sit practice' but obviously I'm holding him at the same time.

Any advice/experience would be appreciated xx

I wouldn't worry at all. My LO is nearly 6 months and can sit unassisted for a short while but not for long. All the babies I know started sitting unassisted between 5-8 months, all different but all normal. I find babies just suddenly seem to gain skills so I bet your LO will be sitting in no time.

My son was 5m. My daughter was 8m and she was diagnosed with hyper mobility. She never rolled over or crawled properly and didn’t walk until she was 18m.

I wouldn’t worry just yet though. Just keep an eye on it and perhaps a call to your HV wouldn’t hurt for some advice.

My daughters 12 now and although it can have an impact (knee dislocations mainly and possible surgery) she managed to dance and join in PE as normal

Have you spoke to your HV at all? Can he roll or tuck his knees beneath his stomach? Is he able to hold his head by himself?

UrsulaBee · 10/03/2021 18:11

Mine were all 9 months, all perfectly healthy

Chelyanne · 10/03/2021 18:30

I wouldn't worry too much, they all get there in their own time.

All ours were around 5mth when they 1st started to do it but didn't last long (timber like a falling tree lol), soon got strong though. All ours took their 1st solo steps before a year old but our niece was 18mth, she runs like the wind now Smile.

Sceptre86 · 10/03/2021 18:51

My dd not till 9 months and she had physio aged 4 to strengthen her muscles. They don't think there are any underlying issues just not as coordinated as her peers but then neither am I

My ds sat at 5.5 months unaided, only for a few seconds at first but by 6 months wouldn't wobble.

Any concerns raise with health visitor or gp. Do lots of baby massage in the mean time.

My first was at 5 months, sitting up and crawling, cruising by 6 months but walked at a year old (I was sure he'd be one of those early walkers). My second, I can't for the life of me remember when she sat up, unassisted but she crawled at 5-6 months, walked at a year. My third sat up unassisted around 8-9 months but he was so much more interested in crawling. He barely started sitting up when he began walking. It was all so much in one go with him.
I wouldn't worry. I know so many kids who sit up around 9 months, walk at 18 months, and they're totally bright, healthy, with-it children. Some of the later sitter uppers and walkers that I know are the most athletic teens I know.

Sorry, my tenses are all a muddle. I'm writing this with Pokemon music blaring through the lounge!

OnlyFoolsnMothers · 10/03/2021 18:58

7/8 months I vaguely remember

Mumof1andacat · 10/03/2021 19:01

8 months. A bit later than some. Ds started nursery at 6 months and nursery weren't concerned. Ds had and still has a bigger upper body and they said that might of been why he couldn't find his balance. No issues since and hes 8 now

CarrotPuff · 10/03/2021 19:06

There's a wide variation, with most sitting up between 5-9 months. Also from what I've observed (and I could be wrong!) bigger babies tend to hit their gross motor milestones later, as there's more weight to support.

Both of mine sat up at 5.5/6 months.

Bringonthemushrooms · 10/03/2021 19:09

8 months. But 2 months later he was standing and taking his first steps

BertieBotts · 10/03/2021 19:10

6 months is on the early side, it's a 5-9 month milestone I believe. Very common for properly unsupported sitting to be more like 8-9 months than 4-6 months.

DS1 was 9 months, DS2 was 8 months BTW.

It has shifted, it used to be earlier - this is thought to be because we are now advised to put babies on their backs to sleep, and therefore they don't spend as much time on their fronts. That's partly why we're advised to do tummy time. But the sids reduction in back sleeping is of huge benefit and later sitting is of no long term consequence, so the consensus is that the milestone has simply moved. But older relatives may be surprised or think it's later than it should be. It's not, it's absolutely normal and fine :)

BertieBotts · 10/03/2021 19:12

The best way to help him learn to sit is to let him develop core strength by giving him the opportunity to lie and roll over. Propping or holding him to sit doesn't train the right muscles as they aren't doing it themselves. Don't worry! He'll get there.

RealisticSketch · 10/03/2021 19:17

6 months-ish for a brief lucky sit of seconds in duration rapidly followed with falling over. To reliably sit without needing to be surrounded by soft things in case of unexpected head to the floor... Aaaages.
Balance games are fun and might encourage. Such as, a game that involves sitting on your knees facing you and you singing a song that ends with tipping them over and tickling. Teaches them to recognise the balance point. I did one that was about horse riding and the last rider falls off, use light support, so they don't fall but part of their sitting is done by them. Hilarious fun and kids still wanted to play it for years until they were too big 😆

5 months

JohnMiddleNameRedactedSwanson · 10/03/2021 22:37

Tummy time, and carrying in a sling. Both really good for core strength. My DS is hyper mobile and delayed on his gross motor skills but has excellent core strength from being carried regularly in a sling from birth. Our physio thinks it has helped to mitigate some of the issues from his hyper mobility.

Babyboomtastic · 11/03/2021 04:51

4m and 5m but I wore both in a sling a lot which I think helps with core strength. This was earlier then a lot of my friends children but your wouldn't be able to tell now looking at them it their peers.

MaryShelley1818 · 11/03/2021 05:15

DS was 5mths. He crawled soon after and walked at 9mths.
However his speech took ages. They're all different :)

jupitermars1345 · 11/03/2021 10:09

My dd at 7.5 months couldn't sit unassisted, roll, crawl etc and at 15 months was walking. :)
She was 9 months when she sat unassisted. 12.5 months when she crawled and walked at 15 months .
She never did the rolling around .
7.5 months and not sitting is very normal.
I also felt like all these babies around me where doing so much more than her but she caught up
