The first 3 months or so are hard. It seems like the baby is just a little creature that eats, cries and poops without much interaction. Then...you finally get a smile! That first smile makes all the sleepless nights and dirty diapers worthwhile, and it's the first indication that there is a little PERSON inside the crying, eating and pooping creature. The first "words" are further evidence that the little creature is blooming into a happy, interactive baby.
We've also been teaching Nate some sign language, just like we did with Olivia. Right now, we are just signing "puppy," "more," and "all done" (when he's eating). Once he starts using a sippy cup, we'll add in "thirsty" and then maybe "milk." It was very exciting when Olivia actually started using some of the signs we had been teaching her, and I look forward to Nate using his signs too. Last week I was sure he signed puppy, but then again, he could have just been flapping his arms and accidentally slapped his leg twice.
Wishful thinking, maybe? I'll keep you posted on both the verbal and sign language progress!
