I got one when we started the family, great for keeping some fitness up when you get a few.minutes spare but need to be on hand.
Child seats and trailers are great when they get a bit older but only useful when the little one is awake and not in the evenings.
I just picked up one on offer at Decathlon, your after quiet so I can’t recommend the model I have. Think fluid ones are quieter but best finding out from someone who has used one.
Congratulations by the way.
