Change of schedule

Any tips on how to change your baby schedule? More specifically bed time. I want to start putting him down am hour or hour and a half earlier. I tried to just go to bed with him so he falls asleep but it doesn’t work.

As the days are longer I want to start having two walks a day (since there isn’t anything else you can do with Covid) one in the morning and one late in the afternoon after mine and husbands dinner but that means changing nap time as well 😑

Basically I want to be one more of a summer schedule 😂 if that makes sense

Thanks
