第 20 週：懷孕期過半！
你的寶寶現在大約有...大小 一隻香蕉.
平均長度: 25.6 厘米
(頭踵長)
本週寶寶發育
寶寶的趾甲正在生長，大腦的感官區域也在飛速發育。全身覆蓋着皮脂以保護皮膚，他們已經有了規律的睡眠和清醒週期，踢腿和出拳的力量也越來越大啦。
本週你的身體變化
時間過半啦！本週您可能會感到明顯的胎動。但也可能會遇到突如其來的腿部抽筋，尤其是在晚上，試着做些伸展運動來緩解。醫生通常會在 18-22 週安排「結構性超聲波」檢查，檢查寶寶的情況。
給伴侶的貼士
便秘可能會讓她不舒服，幫她多準備一些富含纖維的食物，例如西梅或成熟的香蕉。提醒她不要久坐，多起來走走，這對她的舒適度很有幫助。
