Nikolas and his "Big sis" are completely stuck at the hips. They have to be where ever the other is. When his big sis visits she has to drink from his sippies and eat from his bowls. She want him to play with her stuff even though he is too little for them. She shares her horses, barbies and pony's with him. She doesn't mind if he chews on a select few. Yum!! On the other had this has been a adjustment for her too. She wants to be so involved and yet played with by us on her own. She is getting better at understanding the "small" toys have to be played with behind the gate or on the table out of his reach. You can see the joys between them. His Big Sis is sick this week so she called to talk to him. So they talked as a 17 month old and 4 year old would. Silence on one end... She wanted to see him so she asked me to send a picture to her moms phone and I did and she sent him one back. The picture above was taken at Target. She wanted to sit with him while we shopped and they had a blast!!
