I know you can get it in the US, but its very very expensive- so my friend asked me to bring back $100 worth of In the Night Garden stuff for their 18 month old. I did really well for $100 - I had about 7 different things ,which would have cost about $300 or so in the US
I bring back for my niece and nephews Postman Pat, In the Night Garden, British play food/British Play Money (though those are probably a bit older for the babies), Peppa Pig, Paddington, different books that have like Double Decker Buses/Royal Mailesq things (red boxes)/words like "Mummy" in them/Haggis/Highland Cows/Bagpipes, Harrod's bears, Toy double decker buses/London Taxis, Loch Ness Monsters/Highland Cows (like noreim) ,etc...
Its so much fun and they love getting all the different toys from their auntie!
