When your baby can sit up and hold their head up with no problem then you can start introducing pureed foods like Gerber. Im going to do the same thing and make my own baby foods! Around 4 to 6 months. Talk to your doctor they can give you something to get you to produce more breast milk.
I think you can start rice cereal (pablum) somewhere between 4-6 months. Every baby is different! Check with your doctor.
You can also buy a baby bullet or a magic bullet and make your own baby food there are lots of recipes online they can be frozen and saved for when you need them. That's what I'm going to do :)
My pediatrician told us with our first that we could start around 4 months
Not til between 4 and 6 months
Around 6 months if you introduce foods early your risking the chance of her getting food allergies
