If you get a trailer & it doesn't work out (I got a trailer - DD HATED it, would not be in it, screamed, cried...ugh, I didn't love it either as it was a bit tough to pull while riding IYKWIM), I can HIGHLY recommend the Ibert safe T seat. I did a bunch of research before I got mine on front & back seats for bikes & that seemed the best, and for us, it WAS the best! It attaches to the front handlebar stem of the bike & hardly affects the feel or manouverability (sp?) of the bike at all, bub likes it because the are out in front & can see & rider likes it because they can see what bub is up to (turfing shoes overboard etc) & they feel super secure up there in front.

The difference in how my DD reacted to the trailer & the ibert was freaky - run away screaming from the trailer, run to the bike saying "me too, me too!" with the ibert. I think ours was $150? They're probably cheaper now, PM me if you need any more info, but if you decide on a trailer, good luck & I hope your kiddo likes it!
