Yep, happened to Jacob!

He slept beautifully until he was 6.5 months old, then it all went pear-shaped. He started waking up to a dozen times a night (no joke!)

For him, it was all related to developmental milestones and teething doesn't help either unfortunately! LOL

Is Milo learning to do anything new, crawling perhaps? He may have a busy little mind if he's learning new things.........for Jacob, this really was a HUGE thing to overcome and has always been linked to tantrums etc as well......
