Welcome at last!!
Keep enjoying TM - and do join in the chats ...we are a friendly bunch..( I hope !!) well most of the time!!
As regards the Newborn I would not risk your idea without a seat belt to hold the crib...a rear facer if possible.
I took my two home in baskets on the back seat - over 30 years ago but I would not do that now.
BUT hope all goes well with the birth in May.
I became a grandad this week - and am fully besotted!!
