Yesterday evening we were over at DH's parents home. SIL (DH's sister) was also over, with her DD of 16 months and newly pierced ears.
The conversation turned to my dd's (4.5 and nine months) and as always, there were the usual comments of 'dds ears are not pierced...babies feel the pain a lot less' 
to which I always reply 'they don't feel the pain less, they just can't verbalise it'.(interesting bunch arnt we 
)
Anyway!
As I am in the (open plan) kitchen I overhear MIL saying ' one day when dd ( the baby) is with me, I will just take her and get her ears done'.
DH's mother tongue is different to English so I just about picked up on what she'd said, so I walked back into the sitting area bit and said 'what am I missing?' Which was met with laughter and general ha ha ness - and that's it 
They seem to think I'm making a point of 'being different' when I refuse to pierce my dd's ears ( and a million other things) or as a form of snobbery or dissaproval of the way they'd do things. In reality, I'm parenting the way I feel is the best for my dd's. They don't come into the equation at all.
How do you deal with this kind of situation in a way where grandparents feel involved but I also don't get unnecessary holes made in my precious baby's earlobes and other crap
