1. How do you know how much formula to give your baby and will I know when they're hungry/showing signs?
Formula tins have a guide amount on them by age of baby. Babies show hunger, you just need to watch out for it - licking their lips, opening their mouth and sticking their tongue out, moving their head from side to side. These are known as 'feeding cues'. Once baby is crying with hunger, it means they they should have been fed a while ago!
2. Is it best to stick to one brand of formula? So for example, if I give them aptamil but one day they don't have any in the shops, could I give them a different brand? Or would that upset their tummy?
Definitely stick to one brand. Swapping brands can give them stomach ache, which will make then upset and unsettled.
3. What is your preferred brand of formula? And roughly, how much do you spend per week?
the best brand is the one you can access easily at your local shop. Nutritionally they are much of a muchness and no particular brand is "better" or more like breast milk than any other. I can't advise on cost, I've never used any.
4. How many bottles roughly do you need for FF? And what bottles do you prefer?
2 times the amount your steriliser can hold. Then you have a clean set and a dirty set and you aren't trying to sterilise when baby is hungry.
5. If FF straight away after birth, does your milk still come in and if so how long does it take to "dry up" ?
yes milk comes in between day 3 and 5, sometimes up to day 7, Regardless of bf or ff. It'll take 2- 3 weeks to dry up but the discomfort should ease before that.
I've only ever breastfed, but can see the appeal of FF and have FF my niece and nephew when they've stayed. I researched both heavily before having mine and was totally set of FF!
