How to knot the ends when sewing seams

I’m a teach yourself knitter and have nobody to as for help so you guys are it! I’m making a babys sweater, booties and bonnet. I’ve gone as far as I can and it is time to start sewing but I’m confused here. I surely do not want my seams coming apart down the road and am unsure how to anchor the starting of my seams. Most things end with a square knot and you just weave the ends in but what about your starting and ending of seams. Help please??

when I do seam
I start the first stitch then pull the tail in with the stitches to weave the ends in
then when i get to the other end i back stitch to weave that end back in too
thats all

its easy for me, hope it is easy for you too

Thanks! --Mandy
