Get packs of nice cards from paperchase in the sale and use for birthday, thank you and general notes to people.
Dump bags for the slow cooker are amazing! Batch cook pasta, rice, potatoes etc and freeze so all you need is to reheat. Roast potatoes are brilliant done like this! Portion up left over homemade soups and freeze. These are great to take to work for lunch or for a quick weekend lunch.
Have a present box and fill it with things when on offer or cheap. Yankee candles, kids books, sweets, coloured pens etc for birthday presents. Choose age generic items.
We use IKEA plastic bins to tidy up downstairs. After emptying bin. Each child gets their bin and goes round downstairs putting their things in the bin to take upstairs. Once full they put the stuff away in their room.
DC put their dishes in dishwasher, clothes in linen basket, straighten their own beds, put their clothes away (4 year old needs a bit of help!). Hang their towels up and makes sure their shoes are by the front door for the morning.
Store DC clothes in outfits! In hangers or rolled up in draw. Pants, socks, bottoms, tops. Get the next days clothes out the night before. Works well with school uniforms.
Have enough uniform to last the week. Do all uniform washing at weekends. 2 loads and it's done. Whites and darks/colours. Tumble and hang while warm.
