Of course new babies are special etc etc - you will probably be overwhelmed with expensive pretty things which you will have to put aside for growing into and whoops - missed that three week window for that outfit!
Maybe I am a bit strange but I made it almost a mission to buy nothing new for my dc unless I absolutely had to - clothes, nappies, pram, moses basket, bouncy chair, bouncer, high chair, car seat, travel cot and probably more ALL second hand, much of it from jumble sales and charity shops as well as hand-me downs from friends.
This was for environmental reasons as well as economising.
I only buy as a gift from charity shops if it is a close, like-minded friend. But MIL who is like-minded has bought me the odd thing for dc from charity shops.
When they get to about 5 things start to get really expensive, so make the most of this stage while you can! Perhaps you are rolling in money, in which case good luck to you.
There was a time when MOST of my clothes came from charity shops, so although I am not surprised at your attitude, it saddens me.
