Who told you it would get easier? Your Mum? What is she getting you back for? :)
People used to tell us 'it gets better' they still are....but then my Dad always says the first 'X' (relating to how old his eldest child currently is - 40s) years are the worst, don't worry.
It gets different, not necessarily better. Some of those days/weeks/months/years can feel easier as they are not as bad as the bad bits. For some, you'll find it easier because it suits you better (i.e. if child starts sleeping all night, but wakes up at 5am every day - if you are normally an early riser, this will be an 'easy' phase, but not for someone used to getting up at 8am who may be able to handle later/interrupted nights better than you).
I don't want to sound pessimistic, but as someone who has not had an easy baby, toddler or child the lesson I've learned is that parenting is bloody hard. There is no magic day when you wake up and it's all worry and stress free forever more. However, there are magic days, magic mornings, magic nights where it will be fun, lovely, special, etc. You can spend time worrying and hoping the phase will pass, but in that time, you may miss the good stuff and you never know how long it will last. Sorry, babbling here. I guess, don't keep hoping for the good to come, make now the good. Get help to rest, have a break, etc. when you can and eat well, etc. to keep your energy up. Try to enjoy what you can when you can and ease up on yourself (not easy, I know). My DS has been one long whirlwind of wondering why and when it will be easier and these days I am a bit more chilled and more confident in that it just is easier sometimes than others but it will never be as easy as some other parents I know as their kids are just different.
You have a lovely little one there, just some kids take a look more looking to find them. Protesting about being in a pram? Why put them in? At that age DS was super mobile and hated being constrained. Can fight it, or enjoy that they love being mobile/up and about/ nosy, curious kids often don't like being in prams at all. They tend to bad sleepers too in the day as they might miss something crucial going on (like Mum having a much needed cup of tea). Stubbornness is an awesome quality when channelled well - good to have your own thoughts and opinions (horridly exhausting when young, but you will be happy about it when they refuse to bend to peer pressure when older - I hope! :) ).
Sorry this is a babble. I just wanted to write something as DS was/is so wearing and whilst everyone else seemed to get to the stage where kid slept well and they all began to look calm we were still in a frenzy of lack of sleep and stress. Still are though but I wouldn't swap my noisy, curious whirlwind of a child for anything.
