Hi mummies, I am being question by my father why my lo at 4 months can't hold his own bottle while feeding? I don't know that at 4 months I have to start to teach him. How should I start to teach him? dose brand and size of bottle matters?

Every baby is different. Mine at 15 months doesn't even want to self feed. Not because she can't but she just prefers to be fed. Good life kid. You can try using a slimmer bottle or switch to a cup with handles. Pigeon mag mag has a cup for different stages. Stage 1 is with teat. Then progress to spout. Then to straw.
