仕方ないよね

キスメちゃんがお乳が出ないのは仕方ないよね。しかたなく哺乳瓶でミルクを与えると、それで満足したのか、ヤマメちゃんも疲れて寝てしまってね。何よりびっくりしたのは思いのほかキスメちゃんがノリノリでね。

It can't be helped

It can't be helped if Kisume-chan's milk is not coming out. It can't be helped that after giving her the bottle, Yamame-chan was tired, and fell asleep. Above all, I was surprised, because I thought Kisume-chan was in high spirits.

For this one, I'd like a double-check. It feels somewhat wrong, so don't go judging based on this translation.

That's strangely cute.

Last line is more like "most surprising is how well Kisume was taking it".
