Making homemade ice blocks is great for making you feel all healthy and Pinterest-Mum-ish, (“look what we did together with water, a drop of juice and assorted frozen berries! Can’t wait to eat them over hand-painted plates in my perfect garden under a tree decorated with our hand-cut bunting #love#suchagoodmum #lovemylife #mykidsareawesome #organic“etc.,) but the resulting afternoon with the three year old opening the freezer door every two minutes to check if they’re ready while I shout “stop opening the freezer, they won’t be ready for hours!” is really taking the shine off it.
