Thanks so much for all the replies! Loads of great tips! :)
Will look in to those different types of towels and will definitely invest in some more packing cubes.
We are going to Spain (similar area to where we’ve been before) so I know in the Lidl there we can pick up nappies and toiletries. Great shout about the Calpol - have added that to my packing list! Baby is ebf so we don’t need to take bottles or consider formula.
The baby is still quite sicky, so I imagine I will be putting a wash on most days. I really don’t mind doing that and actually prefer to fly home with a case of mostly clean clothes and not a huge amount of laundry to do. I will aim to pack 4/5 outfits each and we can wash/rewear. We won’t be going out in the evenings and the days will be spent either at the beach or exploring some local towns, so we really won’t need much. The weather should be warm enough that jumpers/cardigans are not required in the day.
Car seats - I had a think again about taking them and also looked in to hiring them. The cost would be 10 euro per day per seat, so a total of 180 euro. This seems so so expensive, esp when I could buy brand new car seats for this price. Even though lots of people have no problem at all with hiring car seats with their rental, I have equally heard lots of stories where it’s been a nightmare - no seats available on arrival, unsuitable seat, dirty etc.. I know it is going to be a real pain in the a s to take the toddler one in particular, but I think its the best option. It will only be the getting of these items from the airport car park to the check in desk and then the same on the other side that will be a bit of a faff.
Travel cot - I checked and the accommodations (we are staying in 2 different Airbnbs during our trip) don’t have a second travel cot. Our 2 year old (she will turn 2 shortly before we go) has never slept in our bed before so that would be pretty new for her but also our baby still wakes 2 to 3 times a night, so It wouldn’t work all being in the same room together. She still sleeps in a travel cot at my mothers house and hasn’t tried to climb out yet. My DH and I have had a pretty rough few months with the baby and are completely exhausted and sleep deprived. Thankfully our toddler sleeps really well, goes off to sleep no problem and sleeps all night. At this point I don’t think I could attempt to switch up my toddlers bed routine and try and get her used to sleeping on a mattress ahead of our holiday :(. If she started waking up in the night too or not going down at bedtime, I think it would tip us over the edge! We booked accommodation with 2 bedrooms and the idea was that we would put each of them to bed in the evening in their respective rooms in their cots and we could then cook and enjoy some time together. Out of curiosity, if the toddler was to sleep on a mattress on floor In the second bedroom, how do we know that she would be safe? She could just get up and wander around the apartment in the night as of course there are no stair gates?
Car - We didn’t hire the smallest car, but the next size up. I checked the booking again and it is for a 5 door Ford Fiesta or similar. On the rental companies website it says this size car hire should accommodate two large suitcases in the boot, so I am hoping one large case and the buggy should be fine as our buggy is really compact when folded. The travel cot might have to go in the car yes but we will see. The other bags we are taking are small under the seat on the plane bags, so 3 x small plus a change bag and these will easily slot in somewhere as they are not big.
Thanks again, so so many tips! Really appreciate it.
