Mine are 2.10 and 13mo, will try to answer but tbh, you make it up as you go along
What age generally do toddlers grow out of buggies and move onto buggie boards? What do you do on long trips eg to zoo, where they might get tired walking around? - I always take double buggy, let DD walk if she's willing and chuck her in the buggy if she's being a pain/very tired. I haven't used a buggy board as I love my Phil and Teds
Also how do you coordinate all getting up and dressed and out in a morning, what do you do with the toddler whist getting the baby sorted/yourself in shower etc? - Good question! When DS was tiny I would have a bath or shower when he was asleep but take DD in with me.
had a phase of having a bath, washing myself then getting them both in with me. Now, its a nightmare as they both are very mobile. I have a bath when DH can be available for the DCs, or a shower if not - DD can watch Peppa Pig and DS comes in the bathroom with me and trashes it plays while I get washed.
He likes to throw bottles of shampoo in the bath and pull back the curtain til he's soaked. I really miss my baths
Who do you put in the car first, the baby or the toddler, or does the toddler toddle out whislt you carry the baby? - When baby small, put them in baby carseat and leave them in the hall while strap toddler in. Then fetch baby plus stuff.
Now, they are both mobile so we all walk to the car together, I carry baby, I hope DD doesn't run off, and everyone gets in, I strap the smaller one in first. You are buggered if toddler does a runner while you are carrying a little one and they know you can't chase them as effectively
What about loading car with bags and buggie on your own - do you lock toddler/baby in house whilst putting things in the car, or put the children in the car first then get items???! - Leave buggy in the car most of the time tbh. Load babies in then get bags into car and lock house. Coming home, I carry the shopping into the house before I get the children out. Then I have lots of 'help' unpacking it.
