That’s pretty much the age gap we’ve got. It’s tough going, some stages tougher than others! Be prepared that you’ll be super busy, make the other parts of life as easy as you can. We have a cleaner every 2 weeks, a tumble drier, don’t iron anything that doesn’t absolutely need it, have ‘easy’ meals in the freezer for the kids etc.
Practically, a baby carrier was essential - DD would be happy there if DS needed some time. Also a Moses basket and bouncer, things I could take round the house and ‘park’ her in 😂 we debated a double pram, but we had an uppababy so just got the adapters to fit the bassinet/car seat and toddler seat on together. Glad we did, as 99% of the time DD would be in the carrier and DS refused to go in it soon after he turned 2 - I would go second hand if you really feel you need one but it might be worth waiting until baby arrives unless it really feels essential to you.
DS was in awe of his sister from day 1, he was obsessed 😂 but we made sure he still had individual time with each of us, and we kept him in a couple of nursery sessions a week so DD had time too.
They have their scraps (now 3.5 and approaching 2) but they adore each other. DD talks about her brother in her sleep, they run into nursery holding hands, cuddle up on the sofa together. We can do toddler activities and days out and they’re both entertained. It’s no less hard work, but after the initial blur of the first year or so, it’s the most heart warming thing now to see them together and know that they’ll always have each other xx
