2 1/2 if they were well developed. For literally a few seconds then off again. Done once or twice over the year, other than that I don't do much with anything younger other than turn them out as babies. Then at 2 1/2, introduce having tack on and long lining a bit and hand walking out round the roads etc.
For actual riding [ie, moving!] then 3 1/2 for breaking and light hacking.
Then 4 for starting schooling and 'proper' riding on.
It's their backs I worry about as babies as opposed to legs, as spine doesn't finish till 6.
[That's for cobs mainly that have are here long term.]
Our warmblood, did nothing at all virtually till he was 4 1/2 as he grew like a weed and wasn't physically strong enough for a rider, even at 17hh back then. Granted, he's had the most injuries out of any horse we've ever had. Sods law.
Exactly ditto Christmas sparkle. I have the same type of horse: cobs
Piper was 2.5yrs old. About this time of year (end of summer) he was tied to a tree, minding his own business, when I scrabbled aboard. Not that he cared in the slightest. He's been going for walks with is tack on for ages and was well used to long-reining (much prefered it to being led!) and was used to me leaning on him and standing on blocks to groom him.
I sat on him for about 10secs, gave him a pat and got off again. We did that a few times then nothing more for the winter. He got the same again as a 3yr old. At 3.5ys old my tiny mum sat on him whilst he was led about a bit and he then did some very gentle hacking (half hour walks with me riding for 5mins stretches) over the winter until he was 4yrs old
Massively bothered:
And first time being sat on again in spring as a 3yr old: Toby is far more interested and bothered than Piper! Being ridden is HIS job!
I was asking really as intrigued..... Husband sat on Freddie yesterday for the first time (he's 2.5 now) wasn't even planned as in no hurry, but Freddie didn't give a rats about it, very happy. He is very wide and big at 15.3 and don't think he felt much weight lol..... Can't wait to ride him next summer Cobs rock!
Well Nell is not long 3 and I will probably just sit on later this year, I have leant over her a few times and she has got used to that now, she is a sturdy little traditional cob too, gotta love them
Ditto Katti, my lad couldn't give a crap about me sat on him also. He's somewhat sharp, but over silly little things. Quiet as anything handling wise, but just a bit oversensitive to little things [jabbing, or 'hard' brushes if he's got some mud on him stuck etc or a new person handling him].
It's a standing joke when he's older he'll probably be a prat when it comes to quiet work in a safe school, yet be utterly bombproof in the heaviest traffic or jumping the scariest looking things lol. He's a diamond in my eyes regardless. He's exactly perfectly suited to me, so couldn't give a fig
H (arab) was 4.5. Wolf (welsh x NSH) is being backed at the moment and he's 3.5. Felix (arab) I reckon we may leave till he's properly 4 as he's a bit more of a weed.
I've only ever backed one at rising 3; a connie colt. Other than that normally as a late 3 year old or early 4 year old, depending on when I have the time.
