I should also add that when I say "routine" I use the term fairly loosely. We don't clock-watch as such! Jacob seems to mostly get tired/hungry around the same times each day, but it all depends on when he wakes and how he's feeling on the day, so we're always guided by that.

But his "sleep routine" always stays the same, i.e. each time we put him to bed (whatever time during the day that is) we always go through the same thing - he understands those sleep cues. Generally he goes to bed the same time every evening also - but again, it depends on the day. But every night, it's always dinner, play time, bath with DH or myself, dressed in his bedroom, bottle in his bedroom with a dim light and sitting by his cot, and then into bed. We always say to him "time for sleep, love you" each time he's put to bed too. And I LOVE saying that to him! I always think that way he knows it's time for sleep and always goes to sleep knowing we love him. But again, it's another sleep cue that he recognises. Our Jacob is a bit of a creature of habit like myself and he does seem to appreciate the predictability of these things IYKWIM? So this kind of 'relaxed routine' works well for us.
