From baby to toddler

I saw this video on my husband youtube account, I can't believe Chloe has changed so much in such a short time. She was still baby-talking early this year and don't even know a single alphabet, but just 4 months later she can recognise A-Z and many simple words. I must say she's growing up very fast, not only physically but also mentally, no wonder everyone saying that 2 year + is a good age to start learning :)
