Hi I'm a new mum in Hong Kong from Australia and I have a 4.5 month old. I'm having heaps of trouble feeding him (exclusively breast fed). He cries after about 2 minutes drinking and spits up a fair bit. He lost 200grams in one week and now weighs 14pounds 5 ounces. Doctor said not to worry but she was in a hurry... I tried to feed him some formula but he wouldn't drink it (he doesn't like bottles). Any ideas on what to do?? He also doesn't sleep very well. Hardly at all during the day and wakes about 4 times during the night. I need my mum!!
