Baby playtime is now becoming much more interesting. She will love to play in more advanced ways, such as stacking blocks, cups, and rings. She may enjoy filling and emptying containers with water, though this can be quite messy! It won't just be her own toys that she wants to play with, and you'll be saying "no!" very often, which she might even repeat back at you!
She will now be able to crawl upstairs, so make sure all stairways are secured with babygates, this is vitally important. She could possibly be taking a few steps unaided now, and should be able to walk small distances if she has something or someone to hold onto.
Now is really a great time to give her a variety of toys to stimulate all her senses - musical toys, animal noise toys, toys with different textures, patterns, colours, and shapes. Varied food is now a good idea - she'll appreciate trying out all different flavours and smells.
