Rad Expand 5 Child Seat options

[chonger]

Hi community (reposting because this thread seems to get more viewers),

I am interested in using the Rad Expand 5 to transport my toddler to and from day care.

I am aware of some of the limiting options we have for the Rad Expand 5 and I am having a hard time finding a child seat that is compatible with the rear rack. Does anyone have any suggestions or ideas? I am not interested in getting a trailer either.

Thanks!
