It's interesting and fun to see how Lexi is different from Addison.  Here are some of the ways we have noted they are different:

Lexi is brave - climbing on everything, "surfing" on the rocking chair,  standing on the arm of the couch, and is more rambunctious and brave in the bath.  Addy is cautious: when she was Lexi's age she would sit still in the bath and barely move.  She has always been very careful and scared in the bath.  Lexi is all over the place during bath time.  Addison also doesn't seem to take risks like Lexi

Lexi does not like to be apart from me.  She doesn't like babysitters, even my sisters or nieces whom she sees and plays with often.  Addy is very social and outgoing.  I can't tell yet if Lexi will be but so far it seems like she isn't.

Lexi is a tease and seems more feisty.  She pulls hair, bites, pinches, steals toys and blankies away from Addy.  Addy is usually the victim.  She will stand there and scream while someone hits her instead of walking away or putting her hands up to protect herself.  She never hits, pushes, or pinches.

Lexi is more affectionate to Steve and I.  She gives so many hugs at her own will throughout the day.  Addy didn't do that at this age and still isn't affectionate like Lexi is.  We have been getting more hugs from Addy lately just because she sees Lexi giving hugs and she gets jealous.

When Addy was Lexi's age she slept a lot more than Lexi does.
