hiya (i'm a mum hope you don't mind me tlaking to you ) looked at your site and it looks very good, (DH is darling husband btw) there's an acroms list at the top
anyhow, I think for DH the biggest thing was the moods but he became very very good and aware at tuning in quickly to them, a good example was when I smashed the lid from the crock pot on the floor DH was dying to laugh but darent cos he didn't know if i'd laugh or cry myself, so he tried his best to keep a straight face. I don't think he quite understood how having a baby would effect us as a couple or him as a man, important things for any new dad to bear in mind I think is that the hormones hopefully won't last forever, neither will the screaming and sleepless nights. DH has become very good at the phrase 'yes dear' lol.
also thou, it really really helped he was supportive, mums need the support of all the family which incl's dads, if at all possible, esp for BF mums the mum should be feeding and the dad can do the burping bit (basically get puked on) lol.
DH's is adding you can kiss your weekends good buy, lay ins, ooh and anytime you wanna break for a drink, open your wallet once a week and pour it down the drain (he's joking i'm hoping aboutt hat one! lol)
don't wear new clothes to the hospital, don't try to reeach for the G&A or crack jokes in the, maternity unit (DH got evils not from me I might add)
it's hard until they're about 1 as DH has jsut agreed and then if like us LO is teething it's not really much better than that.
DH thou is a natural with DS being a hands on dad helps it lifts the pressure off of me somewhat - it's important to remember that yes you've been out to work and are tired but any new mum will tell you it's so tiring with a baby honeslty it's not all cups of tea and chatting to our friends (as i'm sure my DH seems to think it is! lol). what's really important for me and makes it easier from my side is that DH will come in at 4.30 and take DS into another room and leave me for half an hour to do tea and forget about everything - it's not much but beleive me half an hour without a child climbing up your leg is really nice! lol.
I know it's prob not much help. but the important thing is to work as a team and to listen - I often say to DH I don't want solutions to the problems I want a cuddle I want a hug - right now in this moment I don't care what the answer is (he's a solution finder). also he's learnt pretty quickly what a balanced meal is and how to cook it - also helps to take turns doing things (am tlaking once baby's here)
and finally cherish every moment. DH wasn't as into being a dad at first as DS was BF and only really intrested in me but now he has a personality & is more active DH is very involved. they're only NB's for a few weeks and once you get thru the first 6 things start to get clearer. hth in someway.
