I will jump in here too, I was 21 when we got married and we fell pregnant a few months later and ever since then I feel like we have been judged from DH's family for not having a house or having ourselves set up etc etc etc My family have been great and extremely supportive from the begining ( after having a really rocky relationship before that)once Elijah was born we had alot of advice thrown our way but I have become good over the years at ignoring it anyway and just doing things my way so it became the same with parenting/ family planning, so now my mum doesnt really offer too much advice but is for the most part supportive of our parenting choices and even when I am feeling down about it she will find a way to make it seem ok. I suppose she can completely understand as she had me at just turned 17 and truly never really got to raise me.
Dh's family are still extremely judemental from me still breastfeeding Elijah to not returning to work, wait til they hear what I am studying and why!

I used to let it really get to me but now I think I have grown in that I don't let it bother me and ignore them or come back with comments that I know will irk them more then they have annoyed me. With the parenting things they think we are strange as we don't do what they do(BIL had a baby 2 months before us) but when comments have been made about it we just turn and say how we think they are weird because of things like cc etc but we just keep our mouths shut as it isnt our business. it has also helped that DH has become alot more comfortable with our parenting and life choices so he will now not compare us to them or tell them this is how it is and that is it.

I just can't wait to tell them that we will homebirth the next baby whenever that will be... hahahaha

I think regardless of your age yes your more septical to have the wait for baby pressure when your young but you also get the opposite when hitting your late 20's but the biggest thing I have had to realise is that it is about me and DH now well and of course Elijah now too but it is about OUR family unit and not the rest their opinions dont matter and if they care for us they will just deal with their insecurities on whatever the subject is.
