I dont think it is. My DD2 also 11 and a half weeks rough routine is.. wakes between 6.30-7am.. bottle.. awake/play.. back to sleep 8am.. awake around 9am.. awake/play.. bottle 10.30am.. sleeps from 11am - 2.30/3pm.. bottle.. awake/play.. sleeps 4.30pm-5.30pm.. awake/play.. bath 6pm then bottle.. play then sleep 7-7.30pm.. i wake her for a dream feed around 9.30pm then she is straight back to bed and sleeps through again until 6.30-7am the next morning.

I dont force her to sleep in any of those time periods, she has just adapted that routine herself and i go off her tired signs. The only 2 sleeps i put her in her bed and she is wrapped is her 11am-2.30/3pm and the through the night one. Otherwise she sleeps in her rocker or swing.
