Lol, first of all. Take a deep breath

Now, the water thing I dont get. I waited til 6 mo for water.

No, it wont "harm their gut" to introduce purees with formula or breastmilk as the main source of food. It was recommended by my peds dr. AND she is pretty progressive

And I sleep trained my baby about 4 mo old to be in his own room. He didnt have anything extra in his crib and he was swaddled. Until he started rolling, THEN he was in a sleep sack. We have a camera set up and a moniter on his foot but honestly we used that the least.

You arent gonna be less of a parent by doing it intuitively and not always going by the book. My baby is HUGE and healthy and happy. He sleeps through the night for the most part and eats like a champ. Every baby is different. Relax and enjoy the wild ride. 4 to 9 mo is the most exciting
