My 3 1/2 month old feeds every 2 hour on the dot during the day.She sleeps from 9pm-6am usually doesn’t wake up. Im just wondering how to go about spacing her feedings out to 3 hours? I believe in feeding her when shes hungry and don’t “watch the clock” but at the moment her routine seems to be 2 hours...When she was waking in the night at 12am & 3am (when she was just born to about 1 1/2 months) she would usually go 2 1/2 3 hours... i have tried to wake her through the night to “dream feed” but she isn’t hungry and just sleeps...any suggestions?

Thanks
