My lo has Startle Reflex any mild sound she wakes up with her both hands up,; sometimes if there is no sound also she wakes up like that.. This disturbs her sleep. Only when she is swaddled she sleeps peacefully so I'm forced to swaddle her whole night ( I use readymade swaddle which is easy to change diaper) . My concern is how long this is going to last? She can't be swaddled forever.. What must be scaring her? Is this reflection of her future.. is she going to be a weak person? I know it's too early but I'm worried.
