They made you go and feed in the loo? F that.
When DD1 was about 9 weeks, I was over at MIL's and DBIL, his wife and DNephew (16) came round to meet DD1. While they were there, I needed to feed her so started, sitting on the sofa in the living room. Next thing I know, MIL (who, incidentally, breast fed all five of her children) started dancing from one foot to the other and asking me if I'd be more comfortable downstairs in her damp basement spare room with the lumpy bed. I said no, I was happy where I was! DNephew only then realised what I was at, he hadn't even noticed before, and fled! I don't think MIL has forgiven me yet for "making him uncomfortable." I didn't, she did!!! But then, her daughter fed Dniece in the loos at our wedding, despite the fact that there were a RANGE of alternatives, a number of which were private, that she could have used. It's been five years and I still think that was mad.
I wouldn't eat in a toilet, and I don't expect my children to either.
Also, every single blessed time someone comes round you don't want to see, retreat to the bedroom with your DD and don't come out until they're gone. I did that when some of my DH's family (who had arrived three hours late) seriously overstayed their welcome when DD1 was about 10 days old. DH came up and gave me a meaningful look at one point, telling me they were thinking about leaving. He didn't bother with that twice.
Glad your DH stood up for you this time. Oh and I remember thinking on Day 16 after DD1 was born, I haven't cried today! she was about 16 weeks before I managed three days without a blub :)
