Triplet mum here.
The first couple of years are brutal but it does get a lot better.
Zoe prams are good triple pram once they can sit in. A converted city jogger is a life saver. Wonderfold wagon works well for transfers from car to playgroup/shop etc
I kept to the feed and change every 4 hrs schedule for ages. Everyone knows where they are upto. Routine is king with triplets- keeps everyone sane.
You can get out with all of them at once, just plan in advance and abort mission if it goes to shit 😂. I.e order coffee in a takeout cup in cafes.
Church playgroups are usually good with lots of helpers to give you a hand. I called beforehand and explained the situation.
Drop the night feed as soon as you are comfortable (pending any required weight gain)
Email your local college and offer work experience for childcare or nursing students - I had three different ones which was great for an extra pair of hands. Also see if you can get a homestart volunteer in your area. Only a couple of hours a week but still useful.
I had a mothers help 1.5 days a week but it's dependant on finances, same with a cleaner.
Lots of helpful advice and support on triplet Facebook groups.
Buy most things second hand
Don't start anything you are not prepared to carry on.
Ignore stupid comments from strangers.
It really is brilliant- congratulations and well done
