Still having frequent night wakes and early mornings help 🤪

been following the advice from possum since my baby was 6m he is now 12m in 2 weeks and nothing has changed much for me he still wakes at least 4-6 times a night but now as I feed him to sleep he will not go back to sleep without breast. I don’t mind so much the earlier night wakes as he does go back to sleep quite well my issue is from 3am he wakes every 1 hour to 30mins and then will want to fully be awake by 4.30-5am. His bed time is 8pm, he naps daytime total 1 hour 2x 30min naps. and we are out majority of the day at parks and walking. I’m not sure what else to do 😓 im confused with all the advice around sleep training and overtiredness. and honestly wondering if it’s just him as a baby 🤷🏼‍♀️
