Is it still safe to use my first born's SSC (bought in 2015 and used weekly until now) for our next baby?

If it's still wearable, I think oo naman. We still use ours which was used by our first born back in 2013. Okay pa naman until now.

As long as hindi pa sya sira. Double check mo nalang din yung mga stitches pati buckles kung okay pa.
