Agree to disagree?

My SO and had originally agreed to not give Ss his bike from Santa for Christmas because of how naughty he’s been we agreed that we would just tell him Santa must’ve seen that you’ve been naughty and didn’t bring it . We were going to eventually give it to him just as a gift once he started having better behavior . And now my SO is giving him the bike . Like what lesson are we teaching it’s okay to act bad and you get what you want 🤷🏻‍♀️🤦🏻‍♀️ and I know it’s Christmas but there is also other stuff for him like some other toys . I’m just completely irritated 😠
