Vomiting/Spitting milk at least once a day.?

i would suggest infant mylicon for the spit up problem my son did the same thing the medicine is for gas so it breaks up gas bubbles there for preventing the whole wet burps your probably getting.... feed baby poop is "seedy" i added a link for a pic of it... and a newborn i would bath her every two days because their skin is so sensitive and plus how dirty could she be... when she gets a month i would do the whole every other day thing and save the everyday for when she starts eating solids and getting messy... and the bouncer thing if its a basic seat doesn't really have support i would wait till she can hold her head better
