DD did this a lot when she was very small, but since about 4 months has basically been a very happy baby. However, over the last couple of days she has had three major screaming fits - the last one went on for an hour and I ended up putting her in her cot because I couldn't hold her - she was throwing herself about so much and trying to bite me. Then I got her to take a bottle of milk and thankfully she has now fallen asleep.
I'm assuming it's teeth, though Calpol and teething powder don't seem to make much difference. However, a small part of me is worried it is something more serious, but I guess that's probably just the paranoid first-timer in me.
The other thing is that this time it seemed to be triggered by frustration - she was playing with some keys and they wouldn't do what she wanted. Surely this isn't a toddler tantrum?
Any advice would be massively appreciated - I am feeling wholly inadequate.
