Honestly jamie went into his own room from about 6 weeks because he was such a light sleeper and my dh snores so bad! So I had him in his moses basket in his cot so he was used to being in the cot if that makes sense, then when he was too big for the moses basket I put him into his cot. Hes slept in it fine because he was used to being in it. We also had a lovely mobil above him which helped. Its all trial and error hun, try putting a t shirt of yours in the cot with him next time, that way he can smell your scent but tuck or tie it so he cant pull it on him.
