So I have recently started back at work after maternity leave, bought a house and have just drawn up a budget. I've worked out that once I take into account childcare, commuting to work by train, mortgage and other bills, I will have £700 pcm of "spends" ie food and all the other bits and bobs! Is this doable?! Any tips to save here and there? It's much less than I managed on before my DS arrived. I'm a single parent. Thanks!
