I am a SAHM of a three year old dd - she will be an "only" child which I do feel horrendously guilty about, which may have some bearing on this.
My issue is that sil has a daughter of exactly the same age and her child seems to have more and more toys and DVDs every time we see her. I've always tried desperately hard to keep up but it's so hard when we are living on one wage - sil and her husband have two wages and free family-provided childcare so can afford much more. I feel awful that the cousin has so much more than dd, especially now dd is starting to notice and ask for things that her cousin has.
Also dd's classmates at pre-school , who have two working parents, all go to lots of activities. I try sending dd to the same things - swimming, ballet, gym etc but it's stretching us so much financially. We haven't had a holiday since she was born either and I feel awful hearing that her friends have been to all sorts of lovely places.
I've never been materialistic at all but I'm feeling really inadequate right now and putting so much pressure on myself to keep up with others. I feel so anxious about dd missing out. How on earth do I get myself out of this ridiculous mindset?!
