We're not on cows milk yet. No real plans to either, I'm happy with follow-on formula because it's fortified.
We have sounds that sound like phases, but I think it is more a case of mimicking and copying noises. For example "hiya", "See ya", "here it is". Words which we think are actual words are Mama, Dada, Nana and this ("iss") - which she uses to get what she wants. Holding beaker up, "Iss, iss" means she wants a drink. Mummy has a biscuit and she'll appear "iss iss", meaning she wants some.
Fully walking here. This week we started outdoor walking, she walked from the Toddlers to the carpark (while shouting "seeya", because she's heard me saying it).
Bought new shoes on Monday. Buckle shoes, so she can't take them off. Given that she's been permanently bare feet before then, it was funny when she tried walking in the shoes. At first she couldn't make her feet work in them.
