Same situ for me! I'm going to not bother and do a mix of baby carrying (the younger one), buggy board thingy or walking independently from my older one ! Just see how we can manage without 😅
I’s go with a buggy board instead, double buggies are so wide it can be a big faff to get on public transport/ around shops. If my second is anything like my first she will be in the sling for the first few months anyway!
Some of the prams have in built buggy boards, might be worth a look x
My little ones going to be 2 1/2 when baby’s born I am working on him holding the side of the pram and get him walking more so we can get away with just a board on the back for a while for when his legs get tired! If I could go back I would of got the bugaboo donkey 😅
