We have 3 daughters that will be here for summer. Their ages are 5, 4 and almost 2. Our 5-year-old has Tetrasomy 18p. She does not walk unassisted, but she crawls and hops and climbs all over everything!! She does not understand dangers and has broken her arm twice just from falling off the couch, so she needs constant supervision. She is non-verbal and is strictly bottle fed. She throws things constantly, not out of anger, but she can throw hard. She is super sweet, but mischievous.
