it depends on how old the toddler is. i dont like the toddler seats because when I have # 2, jackson wil be max. 2 1/2 and will still want to lie down to sleep etc and most of the toddler seats don't recline. I will be getting a tandem - front to back, not side by side - saw a great one at snugglebug in hallam the other day, really compact and only $380.
