My 2 year old toddler keeps waking me up at night

Sooo my son is 2 and this week hesbeen waking me up at night that he wants milk ...he stopped begging for milk when he had turned 15 months but now it’s like he’s doing it again ...I tried just ignoring him maybe it’s just a stage? But it doesn’t work or i give him what he wants and he’ll only take 2 sips and that’s it...is this normal? He’s my first baby by the way so I’m a first time mommy and any tips or advice would help :)
