I have a 2 1/2 year old.
Wife is also a cyclist and fair weather commuter. Dropping our son off at day care sort of threw a wrench in our old routine since the logistics of transporting him by bike (in the morning) can be tough.
Most days I ride and she drives with him, but sometimes she rides and I drive him. In the warmer months we were all able to ride. She'd ride him in with the trailer and I'd meet up with them at the end of the day, hitch the trailer to my bike, and we'd all ride home together. It was pretty great. Sadly my work situation will probably be radically different by the time this summer rolls around
My advice is to be patient and find some ways to pitch in in the morning. It can feel like you're never going to get out the door, but you will.
