Congratulations Donna i have a friend with 5 - 11, 13, 14, 17 and 19 - and she's been a brilliant support, knows everything except not to lick her chocolatey fingers, she's the one i stabbed a while back her house is mad but in a fun way, there's a lovely energy to it iyswim. I imagine the early days are tough though 
Pass it is. IMO it's not supportive at all to take the baby away and give him/her formula. Support is "here's a cup of tea, there's a casserole in the fridge for dinner, have a good cry while he/she feeds and I'll pop him/her in the buggy for a walk when you're done - go and have a soak in the bath." with a lot of positive comments about how the mum is getting on. We don't praise each other enough, nor do we accept praise well.
