We have switched to formula about 10 days ago, as he was on the breastfeeding 12 hours a day & I couldn't cope with a toddler to look after as well.
He is one month old & feeding round the clock every 2-2.5 hours, taking far more than the recommended feeding guides. When he wakes up he's inconsolable if he doesn't have a feed. At first I thought it was a growth spurt, but seems too long. What's the most filling hungry baby milk? (We are currently using Hipp Organic First milk). I'm thinking gas may be an issue and he's on for comfort. Would a dummy help him to go longer?
The thing about hungry baby milks is they're more difficult to digest than first milks. That's why they make babies go longer between feeds. That seems wrong somehow.
Honestly, at a month old 2-2.5 hours isn't too bad. And waking up and wanting milk immediately is normal - both of my babies did this. You'd have to get the bottle ready at the first sign of stirring otherwise it'd be panic stations within minutes
Is he putting on excessive weight? Does the HV think you're over feeding? If not, I'd carry on as is because things are very likely to calm down soon.
Wind could be an issue, and dummies are a godsend for sucky babies. Ignore all the snobs and pearl clutchers on here who act that dummies are Satan's own invention
