hi Jenny,
you should try visit the Toa Payoh Children Clinic, the doctor very experience and she is a PD.
Agreed with twinkle, the suction might cos bit of nose bled due to the tube, but only the out layer of skin, is not serious. But last time my gal did not bleed at all. The tube that the doctor used is really soft type, hence, no worry abt thaT. You think what is the better way for your baby and yourself. Baby cry harder for 1 min but he fill comfortable later. Is worth it.
Abt the milk, i also first time learn from the doctor cows' milk also got allergy. But after i changed to HA, i almost see the result immediately.
Think yr BB and mine same, cant take normal Enfalac. Do consider ya, remember your when jux discover your pregnancy, how excited you are, now, the baby is out, treasure him although a crying baby, he is part of you. haha, this is the phase that i always encourage myself whenever my baby being difficult.
