Refusing nighttime bottle??

👨‍

My son is almost a year old (1 week away) and he has a SUPER balanced diet, eats basically everything we eat throughout the day and we have transitioned him almost fully to milk.

But for the past two nights he has refused a milk and a formula bottle at bedtime and has just gone straight to sleep after bedtime routine.

Is this normal? Should I be worried? Bedtime is the ONLY time that he has a bottle, the rest of the time he drinks out of cups, he always shows and interest when he sees the bottle but won’t drink any more than MAYBE a sip or two and then just falls asleep.
