Haven't RTFT...it was only at 11 posts when I put DD down for a nap and started my housework frenzy!!
Firstly
there could be times when me and baby leave the room for a quick feed - I don't want to be under pressure to master feeding under a cover while I still haven't got the hang of feeding.
You do NOT ever need to cover up or leave the room to breast feed, at home or anywhere else. When I went out for lunch for the first time (DD was a few days old) and I was trying my hardest to discreetly get my boob out and DD latched on DH said to me "just whip 'em out and get it over and done with!!" and that is what I have done ever since (it generally works out to be more discreet as it is so much quicker). The only time I have used a cover has been purely for mine and DDs benefit (mostly my benefit really) when for a few weeks around 4 months she got very distractible and would clamp down on my nipple and then swing her head round at high speed to see whatever had taken her interest [Confused]
As for MIL telling you when she expects to visit/take your baby after the birth, DH and I just went with a totally non committal approach to this, just say you will see how you feel at the time … Rinse and repeat!!. As it was I had an easy birth and good postpartum recovery and so we drove over to ILs (1 1/4 hrs each way) for a surprise visit when DD was 2 days old, and my DM and DB travelled from 4 hours away (stayed in B&B) when DD was 3weeks. Some Mums and babies won't even see a hospital, others will be in for days (even weeks), there is no way of knowing which it will be, so no point planning.
Read the WHO guidelines on breastfeeding, memorise some key points and repeat verbatim as required...MIL & SIL will soon get the message/ get bored.
I like "WHO recommend exclusive breastfeeding to 6 months with no supplementary water" (DD is 5 1/2 months so have been using this one A LOT recently).
When asked how long I will carry on "WHO recommend continued breastfeeding alongside solid food till 2 years or until mother or baby choose to stop".
Maybe find a quote from WHO/NHS regarding dummies if required, and co-sleeping etc.
Then you just need to become more assertive, read up on the broken record technique.
Good luck, don't let anyone put you off breastfeeding. Breast is best, but formula is a miracle invention that has saved many babies lives when breastfeeding isn't an option!
