育児 doesn't mean babysitting, which in English means to look after kids while their parents are gone, but childcare/child-rearing.

p.3 "Is it too hot for you?" > Nope, not what she's saying. She's asking in baby-talk if it tastes good.

edit: ugh, even with 3459385 proofreaders this is still full of bad grammar

rough grammar

every page: completely absent punctuation

p.2 babysitting > child-rearing
p.3 are already taking lead > the lead
p.3 i wonder why they are acting strange these days > this is clearly a past ongoing action. "I've been wondering why they've been acting weird lately."
p.3 chac-chac > ??
p.3 mummy > mummies are in Egypt
p.5 that's why Anna gotta blow it gently > Anna's gotta blow on it gently
p.5 your cock raised up only by itself > idk what you mean by this, but I'm gonna assume it's: "Your cock got up/hard all it by itself."
p.5 it is important to compliment baby > the baby
p.6 mama's having such mature boobs but i can't believe why no milk > mama has... and remove "why"
p.6 to make your milk comes out > come
p.6 dented nipples > inverted

And that's just 5 pages lol
