We don't eat out/order out (well we did once but it was a special occasion). I make/reuse/upscale anything and everything I can. We don't have cable. I plan my shopping and dinner menus ahead. We use discounts and coupons.
Shortly before LO was born we made plans to move into a smaller place. We moved in shortly after he was born.
When it comes to activities for LO we go for free/low cost. We go to the park (in proper weather), the library, and story times. we attend several free community functions. There are a ton of free/low cost activity ideas on Pinterest for when you are looking for something to do at home.
Most of LO's clothes come from consignment or are hand made.
It really is doable. There are a ton of blogs out there with money saving ideas.
