I've been looking at getting a travel size white noise toy to use when out and about, baby due in may, I had Ewan the sheep for at home for my first son and for this baby I've bought a my hummy. I've been looking at the older version of my hummy for use when out and also looked at the tommee tippee travel sleep toy. I know sometimes babies don't always take to white noise, but thinking of just in case.
