Sometimes, trixie and olive look identical. This is either when she (T) finishes nursing, pouts, or smiles in her sleep.
Other times they look and act so differently:
O: not a fussy baby, dealt with the car seat just fine, did not want to sleep at night.
T: fusses often, hates the car seat, asleep by 8 for up to six hours.
My love for them : knows no bounds.
