Add oil are. Your baby will definitely be gaining weight and be healthy and happy. I find sometimes we need to be patient...
Some sharing. My baby is drinking 5.5oz but she really takes her time. After she is halfway through, she doesn't wants to drink and pushes the bottle away. In the very beginning we feel very helpless as she is drinking way too little. We give up. Then realized frm many tries, that after about 20min break (diaper change, playing, chatting), she will finish the bottle gar.
So add oil and be patient ar. Or feeding time runs from 30 min to 1hr15min. After that we just give up and toss out the milk.
She doesn't eat that much, 5.5oz, 5 meals a day. =p
It's just that she loves to sleep and really taking up all the nutrients in the formula.
Her growth is in the 90 percentile line and the doctor said according to her feeding record and her drinking habit, she's a normal baby. =)
She went to the health clinic for follow-up today and weights 7.26kg, above average. She's on A+ formula right from birth. I wasn't succussful in breastfeeding because she's always sleeping. No midnight feeding since 1.5 month and she sleeps through the night.
