Started packing for our first family holiday to Spain next week. Bit unsure what to take for 10mo DS. He's crawling and into everything. Only taking 1 suitcase for 3 of us so need to pack light. Will have access to washing favourites but wondered what's best. Vests/tshirts/rompers etc? How many? Will he just sleep in a short sleeved vest as there is no a/c? I'm in danger of filling a suitcase with just his stuff otherwise!!
