Help!

Ladies my daughter is 11.5 months, ever since 9M she drop to 1 nap daily. Everything was perfect but it’s been two wks where she wakes up multiple times at night just for comfort( she doesn’t cry just calls” mama or daddy” she doesn’t fall asleep on her own so we rock her to sleep)”+ she still wakes up 1 for bottle. Her schedule is wake up 7-7:30 Am - nap 12-2pm sleep 7-7:30 pm. What can I do ? Is it a sleep regression or do I need to adjust something on her schedule? Thanks in advance.
