Hi Denny,

Foldable, compact high chairs are very helpful for small spaces. They comes in a range of styles and prices. I have listed options below from least to most expensive.

If you have a table in your kitchen, another option is to use a chair that clips directly onto the table. Both brands listed below make chairs that very easily and quickly attach to a kitchen table and are also great for traveling.

Hi Cindy,

There is nothing worse than a leaky sippy cup, especially when the water ends up in your bag. Here are some suggestions for leak-proof sippy cups to try!

OXO Tot Sippy Cup and Straw Cups are spill proof and come with lids that also help prevent any leakage from occurring.

Think Baby Sippy Cup is designed to be spill proof and again, comes with lid to help reinforce this.

And lastly, Thermos is a reputable brand of water bottles that also makes kid’s leak-proof bottles.

Hi Megha,

Parents love the Cosco Scenera Next Convertible Car Seat for travel. It is very lightweight, only 9 lbs, installs easily in most cars and is even certified to be used on an airplane if you choose to.

For your Nuna travel crib, the mattress that came with it is the one that is intended to be used with it. They do not sell additional mattresses that can be used with the Nuna aire. This portable crib is quite heavy so they do make a wheeled travel bag to make traveling with it easier. It is listed under Shop Accessories in the link below:

Thank you!
So is there anything additional I can add to it to make it more similar to his crib? He’s a picky sleeper and I’m afraid the mattress that comes with the nuna is too thin

Yes, travel crib mattresses are much thinner than crib mattresses! From my experience, most parents do not find that their babies have trouble sleeping on them and from personal experience, I can tell you my daughter actually prefers her travel crib! But every baby is different of course. I would suggest that if your son hasn't slept in the Nuna before, perhaps try using it for a few nights at home to get him used to it before your trip.

He slept in it “pre sleep training” for short naps and did okay. Hopefully it’ll be fine! Thanks for the tips, will definitely try that before leaving!
