It is clear how the frequency and duration starts decreasing and things start "stabilizing" by around 12 weeks or 3 months. Frequency goes from 10 times a day to between 5 and 6 and nights are looking a little more promising with more than 6 hours of sleep :)
After 20 weeks she started sleeping through the night (at least 10 hours) having 95% or more of the feedings during the day (which we defined from 7AM to 9PM)
I hope this is useful for other parents who are thinking about breastfeeding and its being already a good tool for us to recall this process and be prepared for the baby boy that is coming any moment!
We would love to see others people info to create a better analysis including several babies. If you also used this app or a similar one, please send me your info, Thanks!
