From what I have just watched, it seems that the Midwife visit was timed, for when Family were visiting?
I wish I could put into words, but that just feels wrong. I think that was done by them both, so that if the Midwife was going to question them, that it would be less likely to happen with other family there.
Sarah is happy because it takes off the "pressure" of having to wait in 
Goodness me, her priorities are shot, aren't they?
I agree also re Isabelles hair - it really needed a bloomin' good wash, restyle and a treatment; all three of them needing that, and their Mother.
Why is everything "on the hurry up", running run like headless Chickens all the time. If the Girls needed new school items, buy them online and collect. There is just no structure to what they do - it just screams lazy and can't be bothered.
