Tesco Direct have stick-on bath numbers and letters on offer right now, reduced from £5 to £3.50.
My kids used to love these when they were little, and could stay in the bath until their fingers were seriously wrinkly as they whiled away the time spelling out their names and testing their mathematical prowess.
I reckon I'll have to hide these from my lads if I buy some for the baby though - I can just see them delighting in spelling out certain 'naughty' words like 'poo' and 'bum'. Sigh.
Judging by the glowing reviews, these bath numbers and letters live up to expectations, too. Here's what one happy customer says:
"Reasonable selection of letters and numbers, although they don't stick to the side of the bath as well as some others I've had in the past. Very good that the letters are lower case rather than capitals."
The item explanation on the website says they're suitable for children aged three years and older.
Standard delivery is £3 or you can opt to collect in store for free.
Happy bath time!
