Help with 16 month old

[Purplenpink]

Hello I need some advice/major help please. I have a 16 month old son who recently seems to be developing quite a temper. Is this normal? He's playful not always bad tempered but he often throws food onto the floor from his tray. He will switch the TV off behind the wall and although I say no or 'ah ah' he just says that back then turns it off and laughes.going to the park is a nightmare he screams the minute I try to take him off the swing or slide and starts hitting my hand or trying to hit my face. I've also noticed he's starting hitting for example if I tell him he can't have a certain food or if he's trying to do something that may be dangerous or just basic unhygienic (he likes to drink the toilet water 🙄) I need help on how to discipline him I'm aware he's still young so I don't think he would understand naughty step or corners etc. I try to do a raised stern voice and he just laughs at me. Really struggling with this one. Is this a phase or is it normal?

I can’t remember if it was at 16 months, might have been closer to 14 but my DD went through a similar phase.

I remember leaving the park once in tears because she was such a nightmare. It did get better after a couple of weeks.

When she hit or bit me I’d say “I’m not going to let you bite or hit me, because it hurts me and makes me sad” then either out her in the pram or go and sit somewhere else in the room

DS2 is 15 months and like this atm, the absolute worst tantrums ever.

TBF I recall similar from DS1, they don't understand WHY they can't do the things you're stopping them from doing, because they want to do it so why shouldn't they?

Throwing food here tends to be when he's done and doesn't want that particular food there anymore - easy fix, take him out of the highchair.

Doing things you've said no to, move them away and distract with something else.

Close the toilet lid.

The screaming because he wants to be on the swing is again because he doesn't understand why he's been allowed to be on there for 5 mins and now he's not anymore, another one which is either let him ride it out or distraction with other things.
