A phase or true brotherly love?

Ryan has been super sweet with Dylan. We are wondering if this is a phase he is going thru, or he really knows how to love his little brother...

1. When Ryan hears Dylan crying upstairs, he looks upstairs, says "baby" (informing us baby is crying) and heads upstairs to see his baby brother...

2. If baby is in his car seat or bouncer and cries, Ryan will rock the baby..

3. In the car, if baby cries, Ryan would close the car seat cover (i think he thinks the baby will stop crying)

4. Sitting in the car, Ryan would hold Dylan's hand...

5. If the pacifier drops out of Dylan's mouth, Ryan will try and put it back into Dylan's mouth.

6. Randomly, Ryan will give baby kisses and stroke his hair (without us asking/telling him to do it!)

7. Ryan will ask to "poh poh" (carry) Dylan...

8. During Dylan's bathtime, Ryan would bring the soap and cloth for grandma.

We are truely amazed by his actions. So, is this a phase, or true brotherly love? We hope it is the latter.

Ryan has tried to get our attention too when we are with Dylan. He will ask for a blanket (like Dylan's) and ask for milk, when he sees us feeding Dylan with the bottle. We still see minimal jealousy. He is really such a sweet boy!
