Hello, our daughter is on size 2 mam teats and has been since she was about 1 month old. This is because she was falling asleep and aggressively feeding. I'm looking on mam and the next teat size is for 4 months +, however she's taking 30-40 mins to finish her bottle and is back to falling asleep and not really taking it halfway through. She's definitely still hungry as will scream if we stop feeding her. I wanted some advice on if it's silly to move her up or not given she is 7 weeks old. Very advanced 7 week old baby mind. Thanks!!
