yen2008, staying with ILs, i am also the same...
When i had my #1 i insisted to fully BF, my DH also fully supported me for this.
But when i was on maternity leave, when my baby was crying while i am trying to BF him, my MIL so just came into my room (i didn lock) without knocking...
when she came in i was carrying my bb and top less, my MIL and niece standing at the door .... and my nieve (8yr old) still asking , "ah gim, what are u doing...."
