Hello all I have very active (completely nuts) 2.6 year old boy and a brand new baby girl (6 days). Before having the baby i got DS a likabike so that he would scoot beside me whilst i pushed the pram therefore no need for double buggy. However i created a monster. HE is soo quick although v safe (always stops at the road and waits). EVEn DH cannot run to catch him and he is a v fit 32 year old. So i think the only way is to all be on bikes ,but we have a six day old !So my question is how young can a baby go on a bike seat and what are the best ones any advice gratefully recieved.
