@jennac I thought isofix was fitted to all cars since 2007, not sure what the others are.
It’s a metal bar running along the backseat that seats fix to.
I never used the isofix base as the silver cross came with a car seat that belts in quite well.
The one my 18 month is in has a base fitted to the car seat which he can be in until he’s 4 or his head comes over the top. This uses the isofix.
There is a car seat safety Facebook group which is really good & helpful. We have a local, baby shop near us who are fantastic at going through car seats & travel systems, so I would highly recommend finding one. They also fitted the car seat which helped majorly.
& I found out the other day Britax are German where most if not all car seat safety rules & regulations start from so they are good car seats to have a starting point from.
We have to get a new car before January, ideally before insurance is up in November 
Looking at staying with Vauxhall as only needed one new part in 5 years & our corsa has fitted 2 car seats, Quinny Buzz & when we go on holiday what seems like the whole house.
Looking at a 7 seater but might have to go for 5.
I booked my 25 week midwife appointment for 2 weeks time but I’m actually away so need to get hold of midwife & see what she wants to do.
I would like to join the Facebook group but I couldn’t see it so guess I have to be added.
Exercise wise I am more active than before I was pregnant. I do half hour of yoga a day & try to get to do outdoor gym 3 times a week. My cardio workout is running around after two toddlers.
My squats are getting better & better so I’m noticing a difference.
I’m getting some really big kicks that are getting a bit oooomph so no idea what they’ll be like in ten weeks time.
Sorry if this is long & I missed any questions, I’ve been in bed a hour as absolutely shattered.
