TDs "supporting cycling infrastructure in general" but actively opposing cycling infrastructure that may result in slight motorist detours:
You are opposing safe cycling infrastructure for schoolkids. Own it.

"we can continue to accommodate residents and still develop a quieter space for walker and cyclists."
Residents walk and cycle. The overriding concern is safety, not quietness.

Don't just make a supportive submission. Tell your neighbours, PTA, friends, family etc. why you support it and how it will make a positive impact on many people's lives. Send them the link too. https://dlrcoco.citizenspace.com/infrastructure-climate-change/dlr-safe-walking-cycling-routes-consultation/.

Oh and let your Councillors know how you feel about the trade-off between child safety and a few extra minutes in traffic. https://docs.google.com/spreadsheets/d/1SlckGypOWP54sLrYIzlICz-C8Pa5lDSRSD2OWkFnoPU/edit?usp=drivesdk
