Wehn joshua was little he was unsettled, We think he was the oppostie to costrophobic or however its spelt, as in his crib he wouldnt sleep just cried and cried, but when we put him into his little moses basket which left him not even a cm at the sides he would sleep for hours, I think he must of felt insecure with the space? if that make sense? ..
that was when he was just born till about 5 months old, we hd to buy a bigger moses basket when he grew at about 3 mths old, but then when he got big enough he was fine going into his crib as there was hardly any space left, then when moved to a cot he was ok with it,
he slept with me and his dad a couple of times too,

he's now in a big bed and has been since 17 mths old and he absolutly loves it, he would think it was highly funny that he could just climb out when he was supposed to go to bed, he got used to it and now apparently takes his dads hand and trundles of to his bed when he wants to go to bed,
