It’s a leap, my LO is 16 weeks and still going thru that. If my LO is hungry she will start to smack her lips (instead of sucking on her fist) or fake cry, then I’ll take an empty bottle teat to see if she wants to drink. (She knows how to differentiate pacifier & bottle teat)
Aparts from that, her intake has been on a roller coaster. Her usual intake is 80-100ML/ 2-2.5 hourly. The day before she drank 180ML one shot, subsequently 100-120ML every 1 hourly😰.
The next day…. 40ML lasted her 6 hours. Then she took in another 20ML after 6 hours (starts playing with milk).
Today…. She drinks 80-100ml every 1-2 hours 🫣
