Boy, this one sure takes me back. My daughter Cherokee, who is now 5 1/2, used to climb into the crib with her little sister, who's now just about to turn 4. This was happening when the girls were about 2 & 6 months. I worried about it at first and tried to put Cherokee back into her own bed (we took her out of the crib because she was climbing out of it anyway), but as soon as our backs were turned, back in she'd climb. After I spent a few sleepless nights watching I came to the conclusion that she just wanted some alone time with her litttle sis. She was always very careful not to step on Sequoyah climbing in or to take the blankets from her. In fact, I watched Cherokee on several occassions as she gently laid down beside her sister, pulled the blanket over the both of them and went right to sleep, just as pretty as you please. The girls are still very close and like to take naps together, although, they now prefer to sleep apart at night. I wouldn't worry to much about your Alexis climbing into the crib with your little one. I might still invest into a bigger crib, let's face it,you'll need it eventually anyway. But I wouldn't count on that stopping this issue. Might be better, to stand watch, and just see what happens. Could be this is just the girls bonding with mom or dad's help. It's bound to happen sooner or later anyway. Good luck.
