Everything I have ever got for my daughter is 2nd hand.
We can easily afford brand new things but I CHOOSE to get them second hand.
We have a lovely little baby shop near us that sell just second hand things. I go to charity shops and I use the fabulous FREECYCLE!
I have got the pram, car seat, all the toys, cot (bedding we got as a gift) we painted it white and now it looks brand new. Baby changing table and draws for free, painted it white and it looks great. We got Moses basket. With cot and basket we brought new mattress and that was fine.
People that are just HAVE to BUY NEW all the time are too self concious. Simple. My 10 year old loves going to the charity shops and has always been brought up to appreciate everything. As she is getting older she likes newer clothes but I still pop in their if she needs something for a party or something else.
