Hello, DD is 18 weeks and is constantly trying to sit up or wants to have a nose and see what is going on. At the mo she is in the pram part of our Bugaboo but she's getting really frustrated and I am ending up carrying her most of the time (and she's becoming a right lump!). When is the best time to change over to the buggy part? We got all the bits out today but it says its not recommended for babes under 6 months. Does anyone know if this is down to the position they are sat in so may effect development? I can't keep on carrying her!
