First time Mum and baby doing really well - nearly 7 weeks old and gaining weight well and exclusively breastfed on demand. I think she is going through a growth spurt and has been quite fussy last couple days - feeding constantly one day then sleeping most of another day and crying more than normal and not liking not being in my arms!!! Does this all sound normal? Also last night ( it had been quite a busy end to the day and think she was very tired) she was feeding and kept going for the boob but at the same time was crying hysterically so she couldn't actually feed - nothing helped - so distressing as seemed she wanted to feed but couldn't calm down or stop crying enough to do it. Maybe overtired? Her temp was fine and no other reasons for pain. On the end I laid her down and she calmed enough after a while to feed lying down- it was a brutal hour or so though and not like her! Anyone else have similar during this growth spurt?
