Fussy baby!

Hannah • Texas wife to my Taylor and mama to my sweet boy Easton, and a bull terrier- Lucy. We have #2 coming Feb 2017!
My first baby was too easy! He was always happy, smiling and would hang out in his bouncer for hours happily. My daughter is not nearly as easy! She can't be left alone anywhere for more than a minute without attention. So I'm constantly having to talk to her or be in her face, wear her, or bounce her bouncer very intensely. On top of it all, I feel like she's not as social. It takes a lot to get her to smile and make eye contact, but she will do it! Just not as much as my son. Anyone else going through this? She's 8 weeks, and has been fussy since about 3/4 weeks old.
