I'm needing help with a booster seat selection. It will be for my oldest who will be 5 in Nov. This seat will only be used maybe once a month and for very short trips. She is 44 inches and 39lbs. It will be used when my parents have her for an overnight visit once a month to go to church in. I bought an Avenue 2 years ago but she has pretty much came to the weight limit on it and my youngest is now using it at my parents. I'm not sure which booster will suit her best or the weight limits on them. Looking for recommendations. I'm not in a real big hurry to purchase it. She won't be staying again for at least 3 weeks. I would prefer that it installs with latch.
