Just wondering if I'm worrying for nothing but having a hard time finding milestones for preemies. My son was 7 months on March 17th. He was born at 35 weeks so he adjusted age is a little over 6 months. He can sit with support, ie) leaning on the back of the couch or with my hnd behind him, but as soon as the support is taken away he falls right over. He also shows no desire to sit up, even when sitting up against the  couch he wiggles himself down until he's laying on his back. I normally wouldnt be concerned but it seems I am surrounded by babies grant you all born full term, but both are sitting up without support and are considerably younger than him. One girl just 5 months the other 4.5 months. Just trying to get a general idea of when they should be sitting up                
                             
        
Re: When did your preemie sit without support
My LO was born at 35 weeks also. He was IUGR so he was (and is) very small for his age. He's about 14.5 lbs at 9.5 months now. My understanding is that preemies, especially IUGR babies, tend to have less core muscle strength and tone than term babies. I've found that my LO hits his cognitive milestones right at the average times and physical ones on the late end of average. I think he didn't sit up really well unsupported until the week he turned 7 months old. He just stayed sitting up one day, and we never looked back!
Does your LO get lots of practice on the floor? Is he going to daycare? My DS used to go, and they were fantastic. But I don't think he got quite as much freedom to try to sit up on his own (and fall over ha). He was home for 3 days with a cold, and in those three days, I just put him all the floor constantly when he played. He picked it right up! Same with crawling and pulling up.

My MARRIED Bio
7 months actual age was when he mastered sitting up unsupported. He rolled over front to back early, but he didn't master back to tummy until about 6 months actual.
I didn't think my LO would EVER sit unsupported. Most of the other babies in daycare were doing it around 6 months, and my LO would still flop over after a minute (and then laugh).
It seems like his physical development happens in clusters. He scooted and army crawled for over a month. The week he turned 9 months, he just crawled off - and in the same week he started pulling up from the floor, cruising, and climbed up half of our stairs! Good lord, I couldn't baby proof fast enough ha ha.
She was able to sit up unassisted a little before 9 months actual/ 6 adjusted. Started "army crawling" about 3 weeks ago, just started to "regular" crawl this week. She also started to pull up to standing and go from sitting to crawling, crawling to sitting, etc about 2 weeks ago. No sign of walking any time soon.
Mine were 34 weekers. DS sits unsupported and has since around 6 months actual. DD doesn't, she will sit supported with the boppy or propped up against a chair. DD rolls both ways, & DS doesn't roll either way. Our pedi isn't concerned at all.
They are 7 months actual.
You just explained our LO perfect. He will sit in front of my on the floor and play but when I let go he wiggles himself down to the floor. He's rolling both ways now and it seems as though he would rather be doing that. Thanks ladies for all the info, hopefully he'll start sitting on his own soon!
