This sounds entirely normal, @Shehz21. My sons are 22, 24 and nearly 26, but I still vividly remember when my eldest was going through the 'Terrible Twos' (which is a bit of a misnomer, because they can start before two).
My lowest point - and my biggest parenting fail - came one morning. Ds1 had had a tantrum lasting over 90 minutes the night before, and it was not yet 9am, and he'd been screaming for nearly 45 minutes, and I was in tears, on the phone to dh, telling him I couldn't cope with this any more (I was pregnant with ds2 at this point).
Suddenly it went quiet, so I told dh I'd better go and see what had stopped ds1 screaming - and when I went through to the kitchen, he was standing by the bin, eating tortilla chips out of it!! We'd had some the night before, and had thrown away the ones we were too full to eat - and he was enjoying a delicious bin-snack.
That's not the parenting fail, though - this is. I stood and looked at him, and knew that, if I took him away from the bin, he would start tantrumming again, and I just couldn't face it, so I let him carry on eating and waited until he had had enough and wandered off to play before emptying the bin and finding somewhere to put it where he couldn't get at it!!
He survived entirely unscathed, and is now a strapping healthy man. This was his first and last garbage snack!!
