Well done its not easy.
I stopped a week ago, a couple of days after my BFP. With my other 2 I smoked when I found out and found it hard to stop but did eventually (before 15 weeks). This time i have done it and am so proud of myself fighting those cravings is not easy but can be done.
Cutting down is great and stopping will be easier when you feel 'more pregnant' as it all seems more real then.
Keep it up
as for the feeding row, some women just aren't happy with breast feeding and use formula, big deal. I know babies and now older children from both camps and I don't see much difference in immunity, brain power or the like. So long as baby is happy and growing and mum is happy and relaxed go with what suits you both. Why struggle to breast feed if you really don't like it!
Mum of 2 aged 11 and 8, bottle fed 11 year old, breast for 2 months for 8 year old then bottle all the way. no guilt here and very wonderful children.
