I know every child is different but I do strongly believe in the good bedtime routine of bath, bottle, bed when they are little dots. The bath relaxes them, the warm bottle of milk soothes and fills them (quick nappy change) then into cot, contented and warm and dry.
When our g/son was born (he's now 3) our son and DiL were told to give him his bottle, then give him a bath and then put him to bed.
Caused no end of problems that way around. The bath used to stimulate him awake and he just wouldn't go down in his cot afterwards.
Some new tangled idea from a H. Visitor.
