Chequers - sympathies with feeling funny about being constantly told that you're going to change. It almost felt people were using my pregnancy to just have a pop at things they didn't like or disapproved of about me (you won't be doing/saying/thinking that sort of thing anymore...)
You are NOT going to change, it's just that the criteria you use to make your choices will be different. Your rationale and your choices will be consistent with who you've always been (that's why all mums and all los are different thank goodness), it's just the circumstances that will change. Example:
I swore before I had the wee one that I would not BF in public at all because I felt it was important that it be a calm, quiet thing, without huge distraction, in a regular and familiar place and also because I felt my knockers were a private matter between me Moominpop and Moomintroll - nobody else's business.
Since his arrival I have always taken a bottle with me on outings (we mix-feed anyway) and have not planned any public feeding (unlike many of my peers, who have deliberately organised mutually supportive outings where they could all bf together - safety in numbers). As it happened, on a recent group outing Moomintroll needed food and I was bottle-feeding him but he was mega-hungry and asked for bf after his bottle. Without thinking, or even breaking the conversation I was having I found myself bf-ing him and felt utterly comfortable.
When I made my plan I had absolutely no idea what effect his wee face asking for food would have on me.
I would strongly urge you to be prepared to tell EVERYONE except your DH to bugger off when you're getting the hang of feeding in the first few weeks as the two of you will need to learn together and you don't need to do it under a microscope - v stressful. And when it comes to the crunch with these two menfolk, trust your mummy-whiskers, not your dd-whiskers or your dil-whiskers.
All the very best!
