My friend and her hubby were skint when he went back to uni , they bought amazing eBay bundles for their little one ,Even Asda. We had my godson a few months ago and he got dirty and we didn't have any clothes for him. We went to Asda and got trousers and a top for £6. There is just no excuse for children to look scruffy.
If you're that skint buy stuff in the sale but in bigger sizes so they'll always have new stuff when they grow. Asda had girls coats in a few weeks ago for £4 originally £16.
Some bundles had amazing stuff like , Hugo boss , boden etc and they were large bundles for the whole season for like 25-30 quid
