Nice to see that blue and green snake thing above him - snakes need friends! Only thing with my daughter is she is now so into snakes (only 2 1/2) I found myself watching her today as we walked over moorland in nice spring sunshine in case an adder was around. She would surely pick it up!
Enjoy the journey - each day at that age and certainly each month for the next couple of years, things change regularly. Just as you get used to one phase they change - very exciting and dynamic time. Hope you get good sleep.
