KristinaM - sorry to bring this up again, don't want to start a fight! just incase your friend does consider bfing here's what I have spent, i'm on benefits too so understand why she needs to budget.
breast pump- £30
breast pads- £4.50 for 6 washable pads, only used for a week or so, would need them even if bottle feeding until milk dries up.
sterilizer- was given one which cost £19.99 new, there are cheaper options, cold water sterilizing tablet are less than £1 for 50ish. Again, would need this if bottle feeding.
bottles- £8.50 for 3 including teats.
bottle brush- £2, very fancy one!
nursing bras- £60, but did buy expensive elle macpherson ones, lots of cheaper ones available. wear them day and night so it's worth the expense. m and s has packs of 2 for £18 and mothercare 2 for £25 if i'm remembering correctly
so thats a total of £124.99.
I express directly into the bottles so don't need any storage bags.
I don't think my food bill is more than usual, you need extra calories to stay the same weight but i put on tons of weight while pg and so am eating my usual amount and losing weight. plus saving money by using my milk tokens on fresh milk.
Apart from the money saved it has saved me loads of time, as i'm the only one around to feed bean anyway it would just be extra hassle to prepare bottles.
I understand that some people find it difficult to breastfeed but it's worth giving it a go, apart from the obvious health and financial benefits it's so satisfying and can be really enjoyable once you get the hang of it.
