A week old and guzzling 4oz bottles every 3 hours😅 I'm making on demand and it's just not working, far too stressful when he's screaming the place down😩 how do you ladies do your bottles? I was boiling water and putting it in the bottles and leaving the bottles to cool then putting them in the fridge, then heating for 20 seconds in the microwave before adding the formula. Midwife had a skiddy and said I shouldn't do it like that and should make on demand, but it's just impossible because he's so unpredictable!! Help ladies!!! 😳
