My DC is 21mo and has lots of single words (I counted up to nearly 100 before giving up!) and can join the odd two words together sometimes, so is able to communicate needs in a basic way.
I'm a single mum and have not had more than 2 hours away from my DC (and even that has been on only 3 occasions) since they were born, so tbh I really do think I am burned out and struggling with patience anyway. I also have a lot of stressful events to manage at the moment.
Basically I'm finding myself losing my patience with DC's constant 'mama'. Honestly, they say it 15 times before I have chance to respond, I must hear it 1,000 times a day. It goes like this:
"Mama? Mama?"
"Yes DC?"
"Mama?"
"Yes darling? What is it?"
"Mama, digger."
"Oh wow, yes, a digger."
"Mama? Mama? Mama?"
"Yes DC, what would you like?"
"Mama, digger."
"I know yes, a big yellow digger, look at that!"
"Mama?"
"Yes darling?"
"Mama?"
"What is it darling?"
Ad infinitum. I know I know I know that it's normal. DC sometimes is trying to get my attention, sometimes express a need and other times I have no idea why they need me! But how can I manage my patience? I feel like I'm constantly being shouted at and I'm really overwhelmed as it is, so the total lack of thinking space is tough. I'm close to shouting at DC and it's not fair. I am incapable of tuning it out my blood pressure just keeps on rising 
How best can I handle this? Is there a way I can minimise this, or will it improve as DC's communication improves? I am so close to going "WHAT!!!!!" and have been snappy lately. Am just burned out and it's making my days more difficult!
Help!
