Pushing bedtime later

Pen • 8/17 🌈👧🏼 | 11/19 🌈👦🏼| 👨‍👩‍👧‍👦

Anyone successfully pushed bedtime later, and gotten baby to sleep later too? My kids both go to bed at 7 right now, but it occurred to me that when daylight savings happens that will be 6pm, and they'll be waking up at like 5am, which is just not going to work for me. My oldest naturally gravitated towards a later bedtime and later wake time (usually 8:30/9pm to 8:30/9am), so we never had this issue before. We've put the kids down around 8 the past two nights and my oldest has had bad dreams both nights and my baby has still been waking up early. Suggestions welcome.
