W're expecting baby #4 this summer. We're debating between getting an infant seat or putting him/her into the Radian65 DS1 is currently in and moving ds to a booster. DS is currently 5 yo, 41 lbs and 42,5 inches tall. The baby isn't due until August so ds will be 6 and probably a couple inches/lbs bigger.
So, my question is this: Would you put baby in an infant seat and keep older ds in his 5 point or buy a booster and put baby in the Radian? And what kind of infant seat or booster would be best? This was an unplanned pregnancy and I had gotten rid of almost all our baby stuff so I'm budgeting now for the things we'll have to replace.
