My cats haven't bothered any of my babies, although they do like an empty pushchair! When we put ds1's cot up we left the plastic wrapping on and they then jumped in and straight back out! We got a kitten just before I got pregnant with ds2 who tended to occasionally get in ds2's cot as we didn't have the plastic but never with him in it, he also likes the travel cot when I used to leave it up for work. One of mine initially got quite upset when ds1 had his colic scream fests and would bite me while I was walking around with him and then run off!
I have a ball, it was recommended by my antenatal yoga teacher and I think it's just a normal exercise ball. Was all I sat on towards the end of my pregnancies.
So I would appear my dh's sinusitis is back :( he was horribly grumpy about it all and snappy before bed. I stayed up with him and then just before midnight started to feel sick. Was throwing up from then until 2 and have had lots of cramps so I think it must be a bug and not pregnancy related. Forgot to turn the alarm off so that woke me at 6.40 and he's now making a hell of a racket next to me managing to sleep with the outer tube of his inhaler in his mouth to keep it open and stop him being woken by trying to breathe through his nose! He called 111 at 2 and they got him an appointment at 9.10 but no idea where he'll get antibiotics if he get prescribed more. So I'm wide away, Dh is snoring and the kids aren't up because my neighbours came over and stayed until 10 so they're knackered. So scared to even sip water in case I start being again! Baby really didn't like the cramps, was wriggling like mad which just made me feel even worse, poor little thing! Such ashame when you look forward to one day, hope kids are well when they wake up.
Merry Christmas to you all, hope you have a fantastic day 
I also think one snowball won't do you any harm but everyone has to do their own thing
