I had a routine with DD1 as she needed to feed every 3hrs while I was bf'ing her but when I put her on a bottle at 5 months I just used the same sort of routine, it worked for her.

With DD2 I had NO routine whatsoever till pretty much now, even then her sleep time changes or dissapears depending on what we do. She's 18 months now and both girls have the same routine, but they eat the same food now.

If what you are doing works then why change?

One thing tho, dont stop doing something that might be important just coz she needs a sleep, she will get over it.

Cheers,

Beck
