I put inside the ice bag, yap then I warm it up when she's ready to drink her milk, a bit troublesome but at least she sticks to bottle and her timing for drinking is more stable. And since not a days quite easy to get hot water. :P
I bought already so far is all plastic containers there is no glass containers.. I also wish there is glass but too bad >.< but I use glass milk bottles. :P I think i will use plastic containers to store food but to make hot I will avoid using it.
I didn't use flash cards but more of outdoor stuff, coz I always bring her out, so i will show her, talk to her etc..
