Moms and MILs

Brittney
My mom was nice enough to take me shopping to spoil us with clothes, each time she does that we end up in the bottle isle with her telling me which bottles she thinks are best. I told her I plan on exclusively breastfeeding so I don't want to look into bottles at the moment. 
She told me I'm selfish for wanting to exclusively breastfeed and not giving others a chance to feed!!
My MIL and FIN are looking at cribs for THEIR house as if the baby is going to be spending the night and having slumber parties before they're 2. 
Anyone? Anyone else out there? Do I let them buy it without telling them, sorry but I plan on breastfeeding and the baby probably isn't going to be staying nights with you or am I being to harsh?
