DD is 9 1/2 months. She has been out of sorts all day and yesterday evening. I've struggled to get a smile out of her. She actually took her first steps this morning...she was crying and laughing at the same time. She didn't engage at her baby class at all, sat by herself with her bottom lip out looking really sad. All she wanted to do was hug me. She slept a bit this afternoon. Wasn't fussed about dinner. I got her to bed early but she keeps having night terrors and screaming (whilst asleep). It's breaking my heart, she is usually so happy and smiley..I've given her ibuprofen. I don't think she's teething but I can't think what might be wrong. Any ideas am I missing something?
