Getting more emotional
By now your baby's emotions are becoming more obvious. She may throw a kiss to familiar people, and even repeat it if you clap in appreciation.
Over the next few months, your baby may learn to assess and imitate moods and might show the first stirrings of empathy. For instance, if she hears someone crying, she may start crying, too. And even though your baby's just beginning to learn about her emotions, she's picking things up from you. Over the many months (and years) to come, your baby will likely copy the way she sees you treat people.
Nighttime separation
If your baby sleeps in a separate room and gets anxious about nighttime separations, spend some extra cuddle time reading, snuggling, and playing mellow music with her before you put her to bed. Having a regular bedtime routine she can count on will give her the security she needs to make falling asleep easier.
Your baby will appreciate the consistency and predictability of a set pattern every night, and even better, she'll be more relaxed and more likely to go to bed easily. Just make sure you choose something that helps calm your baby instead of riling her up.
While you can certainly start your ritual in the bathroom or the living room, it should end in your baby's bedroom or wherever she sleeps. It's important to teach your baby that her sleeping area is a nice place to be, not just where she's "banished" at bedtime.
If your baby gets upset as she sees you walk out the door after you tuck her in, tell her you'll be back to check on her in a few minutes. In all likelihood, she'll be fast asleep by the time you return.
Even when you're away from home, stick to your routine as much as possible. It can make it easier for your baby to settle down in an unfamiliar environment.
Remember, your baby is an individual
