Early wake ups

[Griffomais]

My DD is 15 months and has started walking - for the past week she's been wakening up for the day at 4.50am could this be linked to learning to walk and be a development thing? I seem to remember something similar happening when she learned to crawl (it's easy to block these memories out . 4.50am is not a time I want to get used to please someone tell me it's just another phase.

Was about to post similar - my 7 month old was waking between 4.30-5.30 feeding then back to sleep until 7-7.30 now he's forgotten how to go back to sleep! He has just learned how to roll/started crawling and wondered if they were linked...so tired
