As it is holiday time I thought I would mention these. They are new at Mothercare. Infact at my local store they had only just some in yesterday.
They are plastic wirst bands that can be attached round a wrist, anke, cot bar, pushchair, etc. They come in pink and blue. They are reuseable and last for 120-170 hours (so long as stored in special packaging). They only cost £2.99 too.
I thought they looked ideal for babies and toddlers on holiday if you are not wanting to spray them with repellant sprays or creams.
