Overdoing it?

I think SB maybe have been overdoing it a bit, and not have caught up on her sleep. It’s 10.30 and she is stil asleep (though she was awake a 5.30, but then fell asleep when the aklarm clock went off at 6.30…) BB only woke up half an hour ago, and then she drunk 4oz of milk from bottle in one go, which is equally bizarre behaviour? for her. Time for her brekkie and then getting SB up I think .
