Hi, I joined recently after coming across this forum while researching a tandem I was considering. I bought it so that I could take my wife and baby on bike rides along the San Diego coast and river bike paths.
She's six months old, is pretty advanced physically (really good, strong head control), and have checked in with her pediatrician. We tried last night to give it her first shot, but didn't really make it. She was fine with the helmet, and fine with the bike seat, but I didn't get the helmet adjusted properly in advance, so she got fussy while I was trying to get it snug. We compromised and just put her in the seat and walked her around the block to get used to it.
I've got an iBert seat mostly because it was free. My nephew refuses to wear a helmet (at 2-1/2) so no bike riding for him. I just mounted his seat on my bike. However, I've read on here that the iBert's shortcoming is no support for sleeping baby heads. Since I don't have anything invested in this seat, I might buy another one to do some A-B comparison.
Comments and advice are welcome.
(normally, I don't post pictures of my child online, but this one just makes me ache when I see it, so I can't resist.)
