John Lewis have some funky ones online (credit to Francesca for sending me a link!)
My fave sleepsuits for A were from debenhams, pack of 3, one is dark green with 3 monkeys on and others have jungle animal print all over.
Sainsburys had some really nice ones the other week - a pack of 3 one is navy with white aerorplanes all over, one is red...cant remember rest, I think they all have a plane of some sort on. Also 25% off until Monday.
