How are you going Salsa? Have things improved since your post or are they the same? I'm guessing that your bub is overtired and that is why he won't sleep. Babies as young as yours can usually only handle 1 - 1.5 hours of wake time before they need sleep. Catherinemoses gave some great advice about watching for tired signs and then putting your bub straight to bed. He may yawn or start grizzling a little or rub his eyes, if you see him displaying any kind of tired sign, pop him straight to bed. He needs LOTS of sleep at his age!

You don't need a strict routine at all, you can just set up a basic pattern for the day and he should start finding his own natural routine. For example: wake up, have a feed, play time (or mum's errand-running time ) and after being awake in total for 1 - 1.5 hours, put him to bed. Repeat throughout the day until bedtime. As he gets older you can start stretching out his wake time.

I hope this helps
