Icy I see, is Crystal gaining weight well? If she is, your BM is enough. Think better to tahan until 4 months if you can cos after that she can at least try solids. Of course, 6 months is WHO's gold standard for TBF. ;P
Yes, RaeAnne is learning very fast too. Today, her PG teacher was surprised that she can say 'gingerbread man' cos they did that for arts and craft. Explained to them that she has been eating gingerbread boy biscuits since Xmas time. Today I dig out her old Xmas tree paper hanging (done at PG too) and she started singing Jingle bells, jingle bells. Which means she remembers the association with Xmas.
Nowadays, I try to spend at least 30 mins with RaeAnne doing or playing intellectual activities eg. read stories to her, do her kumon books, or do jigsaw puzzles, or teach her to count. Not a lot but better than nothing at all cos at ILs place, she gets 'free play' all the time.
Aqua, I'm Rabbit and RaeAnne is Piggy and my ally. Today, I cajoled and nagged until she said sorry to me for wetting my bed with my water bottle. She opened the cover for me to drink water (cos she saw that I'm pumping) but she can never close the cover properly.
