i would have to say to go with your momy instinct, 'cause i remmember my Ped. told me not to swaddle my DS, and since the Ped. wasn't going to be there in my house putting my DS to sleep, well i decided to swaddle him, inspite of what he had said. Another example, he told me to start solids at 4MO, and i didn't feel confy with that so i waited another month, so i guess you must do what ever YOU feel is right. Personally i wouldn't feed her every 3.5hrs, but also how is she taking her milk, does she seem hungry at the 3hr mark?
