My Ho Yin is like that recently.
He is 4.5 months old and 7.5kg.
He only has about 4-5oz milk 5 times a day.
He sleeps from 8:30pm to 6:30am and when he wakes up, he can only take 4oz.
Now I need to feed him for an hour to make him take about 5oz.
We are going to try to feed him 4 times a day and see whether he will be more hungry.
If not, then I will start to give him so rice cereal (mixed with formula) and see whether he will take more.
I m not too worried although he is losing some of his reserve (fat).
Well, he still has a bit to lose!!!
Try hard!!!
I feel the same as you.
My ho yin was quite chubby and now he is losing his fat (heart breaking)!!!
However, I cant force him to eat as he knows how to spill the milk out now.
He gets a bit better after we feed him 4 times a day.
he eats a bit quicker for the first 4 oz but very hard to take more after that.
I was feeding him for an hour but my hubby said that I shouldnt do that.
I will try to stop after half an hour and hope that he will have more next meal.
I will start him on solids next week (he will be 5 months).
although I dont really want to start solids with him that soon, I need to do it as he just doesnt take enough milk.
Try hard!!! I believe that they will get better!!!
