Congratulations @Shockedmumof3 ! I was exactly you a year and a half ago. I have a 4yo son and twins girls who have just turned 1yo! No twins in the family either so it was a complete shock.
My advice is to try and get them in to the same routine as early as possible ie if one wakes in the night needing to be changed or fed, wake them both and change and feed them both at the same time, it really does make life easier when they eventually wake at the same time and have the same body clock so you can at least get a more solid chunk of sleep.
If you can, try and carve out some alone time for your 3yo. Once you’re in a bit of a routine, if your partner (if you have one, sorry I don’t want to assume) or a family member can watch the twins for an hour whilst you take your 3yo to the park or just colouring or reading at home with him, and vice versa if you have the twins and your partner gives your 3yo some 1:1 attention. When your twins arrive, obviously you will love them so so much, but at the same time, I felt an immense amount of guilt for not being able to give undivided attention to my eldest and I honestly think emotionally, that’s what I found the hardest.
You will soon get into a routine and find what works best for you and your family. Don’t feel guilty about any decisions you make and just take ‘well meaning’ advice from others with a pinch of salt.
If you are planning to formula feed or a mix of BF and formula, definitely invest in a Tomme Tippee prep machine for the home and Nuby Rapidcool for when you’re out and about - They’re a lifesaver and speed up making a feed when you have two screaming babies!
If your 3yo can’t manage to walk for very long or is generally lazy (like mine!) and wants to sit, definitely invest in a buggy board. If you’re not sure what twin pram to buy yet, you can get some universal buggy boards from Amazon that work with most prams or specific buggy boards for specific prams such as bugaboo that just click on.
Huge congratulations to you! When you see your eldest hugging them and them eventually all playing together, everything will be worth it.
Not ‘double trouble’ but ‘double the blessings’ 💕
