Reddit mentions of TROCKOLINO Nice 'N' Dry - Rain Cover for Child Bike Seats – Black

I'm very glad to hear that :)

> Dropping of our daughter to kita is a bit more complicated with the bike especially in the rain and since the kita is so far away.

I can sympathise - half an hour on the bike, in the cold and wet, with a toddler on the back is anything but easy. The longest Kita-commute we ever had was about fifteen minutes.

> We had a steep learning curve since we never biked in California in the rain (it rains about 10 days a year in San Diego) and we definitely weren't prepared for the rain when we moved.

Other tips which may help:

• I found that having good gloves makes a massive difference to feeling comfortable in the rain. There are special biking gloves with reinforced palms (like these ones), but any light but waterproof set of gloves will do. They also double up as your go-to gloves for cold-but-not-super-freezing weather. I break out my insulated skiing gloves for a few weeks a year, when it gets below freezing on a regular basis, but the insulation makes them stiff and heavy, so I only use them when I have to.
  
• When it gets colder, I find that a light balaclava (example) works wonders. It's thin enough that it goes under the bike helmet, and the mesh around the mouth is porous, so you can breathe through it - but it keeps your face warm, and the rain/snow off of your face and neck. Children probably need something a little thicker (e.g. a Schalmütze, which is great for colder weather in general), which means the helmet won't be well seated on their heads - but that was a compromise I was willing to make.
  
• I usually dressed my daughter in a some waterproof trousers (Regenhose; an example - the non-insulated ones were fine for the autumn, but we switched to the insulated ones in the middle of winter) and a rain jacket. Additionally, I usually had a cover for the child seat (to cover it when my daughter wasn't sitting in it), but I found that I could use it to cover her legs and feet when she was in the child seat, which helped to keep her feet dry. She liked it, as she said it felt like she had a blanket over her legs.
  
• If you find that you're skidding on the wet ground, let a bit of air out of your tyres. While it will increase the rolling resistance a bit, it will also increase the grip on the road. Obviously, this has its limits - I draw the line at ice on the ground; I take public transport or the car for the one week a year or so, when it's just too slippery to cycle safely.
  
  As our children are getting bigger, and particularly our eldest wants/needs to be shuttled to more and more activities, we bought an electric cargo bike this summer. It was an expensive investment - they cost about as much as a used compact car - but it's been so worth it. We can now carry both children, plus shopping/rucksacks/musical instruments/random stuff they bring home from kindergarten with ease. The kids get a great view from the front (and I can see what they get up to, which always bothered me with the trailer), the rain cover keeps the kids dry, and the rain poncho keeps me dry too. I think the last time I used the car was three weeks ago, when I went to Ikea to buy some furniture. A cargo bike is definitely not for everyone - for one thing, you need a place to park it (which is tricky if you live in an apartment), and it can be a bit unwieldy - but for us it's allowed us to leave the car at home even more often than before.
  
  > I know there are many people that have more then one kid and no car and are doing just fine. I guest we just need to adjust more.
  
  Don't be too hard on yourself - we didn't get to where we are overnight. It took us years of figuring things out, and of getting out of our comfort zone, one little step at a time. You're already doing great by cycling to work and to the Kita. I even know a few families who managed to ditch their car completely - while we're getting there, I don't think we're ready to sell our car just yet.
  
  I wish you all the best! :)
