Minky- I've had strawberries, orange and kiwifruit in the net feeder. Amber just chomps into it. Its good because she cannot get any chunks into her mouth. She doesnt like to hold it for long herself but will keep her mouth open for us to feed her!
Prama- How much milk is poopy having throughout the day? I think as long as they have a minimum 600 mls (i could be very wrong) per day they are ok. But hey if he is healthy and thriving etc...
The net feeder has big net/mesh thing where you put fruit or vegies in. You then screw a top into it. The babies can then chew/suck on the chunks without choking. I have the sassy brand and got it at Big W.
