I started taking my son swimming when he was 2 months old, every week. From 4 months, he went to baby swim classes weekly and loved it. He grew more and more confident, to the point when by April this year (23 months) he could swim a tiny bit with arm bands on. We moved house in May and it took a while for me to reorganise the lessons. I told him yesterday we were going swimming again and he was very excited - he even got a towel ready! Very excited this morning as well. He was fine getting changed and walking to the pool. When we got there, he refused to get in and promptly stayed on the side shaking his head saying 'no'. When I lifted him in, he went absolutely ballistic - screaming and thrashing and screaming - ruining the class for everyone else. What has gone wrong? Is it that I didn't take him for 3 months? He had that break last year as well and was fine. I have no idea what has happened and I'm very upset. Any thoughts would be greatly appreciated.
