I've got a small 10 month old, who sits in the back most of the time, I thought I could get by with just a coat and blanket along with a lambskin, but he already seems cold so I want something lovely & snuggly for the colder months. Is the P&T one worth the money or chould I go for something else? Ideally I'd like something to last for next winter too - so it would be good if it also fitted on a maclaren.
