Thanks for the posts and honesty gents.
She's now coming up for six months and has honestly been the greatest thing I've ever achieved. Pass The Dutchie, lots of love for your post; there's been split seconds of 'FFS give it a rest now' but nothing thats really tested us... until now. Little un is teething and she really is struggling. Thankfully my missus has been fantastic and as advised we've tried to take shifts when the going gets tough. Noone warned me how boring the first months are, they don't do anything!
Now she's rolling, has the most amazing laugh, interacts and is showing very early signs of crawling.
