HABLO isn't a baby monitor . Today , Parents precisly new parents are almost engaged ( work, meetings... ) +baby crying is like annoying and depressed things so we propose a solution that could be a relief for this problem and genrally parents don't know why his baby is crying so we can facilitate the communication between them

Yes plus the baby cry is perfectly tuned to wake you up, so any alert this does will be inferior. Plus if you recognise types of cry you’d lose that fidelity through this.

I’d consider pivoting this into a sleep study device. Ie collecting stats so that you can reflect on the quality of baby/toddler sleep with recommendations to see a doctor if appropriate.
