Dee~ I asked my MCH about weetbix and she said not to give it yet as there was a too much fibre for their little tummies to handle.
I think the most important thing you can do is go with your instincts. MIL's can be a pain! I am so glad I don't really talk to mine!
I hope your flu goes away soon. These babies don't really leave us much time to get sick. I was sick yesterday and William and I stayed in bed til 3pm. Lucky for me he was happy to play and nap in bed with me.
