So, from being totally stationary at almost 12 months, DD has been busy crawling for a couple of months and has now worked out how to pull herself up and consider cruising.
However, this new found skill seems accompanied by continual frustration. Its on and off, but she's very irritated in the pushchair. This is a total change for her.
She may be coming down with something (she usually is) but has anyone found spells of increased tension and irritability during the development of new physical skills like these?
