Plotly: Change order of elements in Sunburst Chart

I am currently using plotly express to create a Sunburst Chart. However, i realized that children are ordered alphabetical for nominal values. Especially for plotting months that is pretty unlucky... Do you know how to handle that issue? Maybe a property or some workaround? Below there is an example so you can try it yourself. Thanks in advance!

import plotly.express as px
import pandas as pd
import calendar
months = [x for x in calendar.month_name if x]

#Create Dataframe
data = []
for m in months:
    data.append(['2018', m, 2])
df = pd.DataFrame(data, columns=['Year', 'Month', 'Value'])

#Compute Sunburst
fig = px.sunburst(df, path=['Year', 'Month'], values='Value')
fig.show()

Please Check this out. I have just added values to each months instead of hardcoding 2. So the corresponding month matches with corresponding number.

January-1, February-2, ... December-12

import plotly.express as px
import pandas as pd
import calendar
months = [x for x in calendar.month_name if x]
#Create Dataframe
data = []
for i,m in enumerate(months):
    data.append(['2018', m,i+1])
print(data)
df = pd.DataFrame(data, columns=['Year', 'Month', 'Value'])

#Compute Sunburst
fig = px.sunburst(df, path=['Year', 'Month'], values='Value')
fig.show()
