I have been learning/using Japanese for the past 16 years and now that I have become a mother to my 3 month old son, I would like to bring him up exposed to both English and Japanese. I haven't had many interactions with small children so don't know much baby/child specific language. I would love some suggestions. E.g. Can you use 愛している to say I love you to your child, or is that only for use with a significant other?
