Stress, exhaustion and just the mere idea of friction can cause us to choose the path of least resistance. I think that is where you are right now.... it sounds like you are choosing the path of least resistance... I cannot blame you... I reach that point about 5 times a day with various aspects of my life... not just with my kids. Life is a juggling act - some of us have more balls in the air than others. It sounds like you are trying to put more in the air than you really need to. Pick your battles, and decide what is most important right now... bottles? stand your ground, be firm but make him want to change it... tell him he's getting to be a big boy, and bottles are for babies.... etc. Or pack up all the bottles and hide them... get spill [roof sippy cups and say thats all he gets, there are no more bottles.. ask him to help you look for them... he will see for himself that there are none.... just cups.
Then work on the paci, but I really dont think all these changes are good nor are they necessary... dump the bottle then work on getting him excited to have a baby brother, and prepare him for that change - this is a huge one for him....
Potty training a girl is easier... i won't lie. it's not because of their parts, or because they're smarter - not saying that at all.. .fact is, boys potty train later than girls typically. Now of course there are exceptions, but most of the time, the boys just are not ready at 2. If he has no interest, it will take you twice as long, and be twice as hard. I don't have any plans on starting my son potty training until at least 2 1/2. UNLESS, he shows interest earlier. in your case, that would be right around the time new baby is born... so hold off. I remember hearing when you restrict fluids before bed, and they wake up with a nearly dry diaper,... they are ready to be potty trained. My daughter would sleep so heavily, she wasn't overnight trained until almost 5 - the signals to pee just weren't waking her...
So, pick your battles mom... one step at a time, and relax.. no kid went off to college drinking a bottle at bedtime...
as for the paci - I dunno... I am sure most would disagree... but unless he is walking around with it all day long, I see no harm in letting him have it for a while. he finds comfort in it... My dentist told me that it doesn't start doing damage to their mouth until about 5 yrs old, and even at that, it needs to be in their mouth a lot. If your son is like my kids, they keep it in until they fall asleep, then it falls out. I typically leave the paci in their bed, because that's where they use it. Give him some time on that one.
Good luck to you K.. congrats on #2 :)
