Swaddled 9wo has a huge startle reflex.HELP

[RENI]

Me again,
my baby is still sleeping on me the best but since I had enough today I put him in his cot awake and we did shush/pat.He cried I picked him up ,patted him and put him down again continuing the patting.
He feel asleep and I stayed there to watch him.He has a massive strartle reflex and wakes up because of it.
He is swaddled and just by me putting a hand on his chest he went to sleep again.
Do I double swaddle him? what are solutions are there?
I have yet to figure out what personality my baby is but I am thinking spirited.
Thank you for your help

If you're able to, I'd do holding through the jolts (httj) until he's past the jolts and into deeper sleep.  It normally takes about 15-20 minutes...

The moro reflex normally disappears around 3 months of age.  I know my kids still kind of startled even after that age, but they no longer would wake themselves up from it.  I also noticed that the jolts were more likely to wake them up if they were overtired or overstimulated.

What kind of swaddle do you use?  Maybe there's a different one you could try if you're not able to do httj?
