Crying baby 15 months: can Bach flowers help you?

Good morning I have a 15 month old girl and since she was 9 months old (at that time the first tooth came out) she wakes up crying even 4.5 times at night and sometimes even when she sleeps in the afternoon. I went to a herbalist’s shop and he gave me Mimulus for fear but it only worked for a few days, i.e. at night he woke up once but always crying, then I came back and he gave me Resource remedy along with Mimulus. I believe that it is not fear or not only that, I think that she is too attached to me (she is with me 80% of the time) because when she wakes up in the night she sometimes takes my hand and falls asleep like this (I am still breastfeeding herin the morning and in the evening to sleep, I think she uses her breast as a pacifier since she never took it) but as soon as I remove my hand she wakes up, maybe because she falls asleep at the breast and then wakes up alone in the bed, even during the day when I leave her alone in the room sometimes she cries. During the day she is a serene child, in the park she greets everyone, always smiling. Do you think I should try another flower? I need some advice because I’m exhausted and now I’m taking Resource remedy for stress too . Thank you
