My boy is 4m old and has strong head support he's also on the much larger side in terms of size! What age did everyone put their bubas in the buggy? He's very curious and nosey and loves to see what's going on around him but I do feel 4m is a little young. Then again babies are all individual so it might be okay for me to try it out on a short journey to see if he likes it, or do I wait til he's atleast 6m?I have a silver Cross bad boy that has 3 attachments one being pram, one being car seat and the other being the buggy.
