Is this normal toddler behaviour?

[Sparrowlegs248]

Husband and I disagree.

Ds is 20 months old. This evening we had been out and had dinner, got home around 6. This is unusual. Ds wanted a drink, was given water in a sippy cup. Proceeds towards living room with it. Food/drinks not allowed in there, so is told to have a drink, put drink down then go in living room. He stands pulling at the door clutching cup. Wailing. Wails when cup taken away, wails when not allowed in living room with cup.

Normal toddler behaviour or not?

Thanks imsticking I think.hes beyond anyone, other than himself', helping.

It's draining though and has me questioning myself, hence my post.
