He’s only going to learn by doing it so you need to cut him some slack. Boys/ men are generally not socialised in families with how to look after young children ( I’ve met a few men who did not hold a baby until they had one!) You either need to show him in a non negative or judgemental way how to do things or give him space to learn for himself. As long as baby is safe it does not matter if things are done ‘your way’, he is also a parent and is entitled to find his own way how to do things too.
I agree with @Amy. When my LO was born my partner was so nervous as he had no previous experience around babies. I showed him everything and guided him throughout but making sure along the way that I was patient with him as I could see how nervous he was about looking after a little tiny human, its just about working together and navigating through this new chapter. He doesn’t do things my way and has found his own way of doing things and yes there were times at the start where I was itching to jump in and want things to be done a certain way but i’m really proud of him now, his confidence has grown and his bond with my LO is amazing. It’s just time and patience. Work together, make compromises, as long as your baby is safe allow him to learn, giving him support throughout.
You need to step back a bit. I did this alot at the start and it isn't fair on dad. It's hard but remember that there is a reason you're with this man and chose to have a baby with him. Trust him. My partner does things differently to me and it takes all my willpower to not say anything. But I don't say anything because at the end of the day he's their dad and I trust him. It's normal to do things differently and it's good for baby to experience different needs being met with different people. Don't forget that this is all a huge adjustment for dad too and he needs support and reassurance. Telling him how to do things and criticising him do not provide a sense of support. Just bare it in mind.
Are there any classes you can both partake in together? I attended a few free ones whilst pregnant hosted by @thehonestmidwife on Instagram and @thebabyacademyUK on insta too. They were really insightful and were live web seminars :) all about how to care for baby etc! Also me and my partner often send each other reels from Instagram on top tips which we both find helpful. Ways of gassing baby, clothing them easier, holding etc!
