DD is 16w and seems to be getting fed up of her pram. She's fine for a while, or if she's asleep, but eventually starts crying. She's very alert and likes to be able to see what's going on around her, so I wondered if the pushchair might be better. My Mum thinks it's too early, as she can't yet sit unaided. She holds her head up very well though. Thoughts from experienced mums?
