I have read that at 2 months-old your baby makes real progress in communication. And that’s true! I started mimicking the ‘nga’ ‘aye’ ‘kha’ sounds she was making since 1.7 weeks. And by 2 months we were having a two way baby conversation! It was a lot of incoherent noises but we were properly communicating (yay!). I also spoke to her a LOT from 5 weeks or so on – for one, she was the only one fascinated by my moving lips and constant babble; and two, it really helped her start communicating on her own. Now we have little conversations of our own, every day. There are even times when she’s all smiles, talking to herself for a few seconds – it’s too cute!
