We had Gelert junior ones for our 4 and 2 year old and they were a bit longer bbut still ideal - no probs with slipping down the bottom end etc! They're mummy shaped and were a bargain at £8!
You either have a very large daughter or you bought a Nitestar Baby, which IMHO is really only for kids up to about 18 months old, whatever it says on the label. My three all outgrew it after one year of use each.
Next step up is the Nitestar Midi or the Nitestar Convertible...
Yep its a nitestar baby. I'll try to get a midi or convetible - need one for the weekend four our first trip, all a bit lastminute as just bought a tent today.
I have to say that responses here are really quick.
We have the Vango junior, real cheap at Go outdoors. Went camping in mid July, but could see your breath it was so cold. Naturally, was worried about my 2 year old being warm enough. He did have his woobie on top of him over the sleeping bag, but he woke up snug as a bug and warm as if he were at home in his bed. Great bag, think there is a pic of him in my gallery.
