4 months old is a fun age, don't you think?
You can roll over...
You can roll over...
and sit up...
and play with toys...
and laugh...
and have play dates that are just for you (even though big sister wants to crash the baby party)...
You are also SO adorable with chubby feet...
and sucking your thumb...
and loving on your sister...
I love this stage. And I know it's going to be over TOO FAST.
