My baby is 10 weeks old tomorrow and normally sleeps well through the night perhaps waking up once or twice for a feed between 10pm and 8am! Today I took her for her first baby swimming and then she had a nice warm bath when she got home. Since about 1pm today she's been fast asleep and woke up once for a feed. She doesn't usually do this during the day.. I'm normally fighting to get house work done. Should I be worried or could swimming have really taken it out of her?
