I am so tired and about to start back at work next week.
For the past few days by baby has been waking for the day at silly o'clock. Friday morning it was 3:30am, Saturday 5:15am and this morning 4:00am. He used to wake between 6:00am - 6:30am.
I just don't know what a going on.
He has always been a crap napper during the day but his overall sleep is just terrible at the moment.
I'll put out day yesterday down below. Perhaps someone with a lot more knowledge can tell me where I'm going wrong or offer reassurance that this is a phase.
5:15am - wake
6:00am - 7oz bottle
7:00am - breakfast of porridge
8:30am - took baby upstairs to settle him for a nap. Nappy change, into sleeping bag, story read to him, Ewan the sheep playing.
Took 45 minutes to settle him.
9:15am - napped for 1 hour
10:15am - awake, dressed and out with me to run errands
11:00am- lunch
12:30pm- fell asleep in the car but woke up after 10 mins
1:30pm - 7oz bottle
2:00pm - nap downstairs on the sofa on me. Took 5 minutes of screaming in my arms to nod off. 
2:30pm - woke up
5:50pm - getting tired so took upstairs to play in his cot while we started to get his bath ready
6:05pm - 6:15pm - bath time
6:20pm - Pj's, cuddles and a bit of crying and fussing when put in his sleeping bag
6:30pm - bottle and then cuddle. Put in cot very drowsy but awake and had to settle to sleep with a hand o the chest. Was asleep for 6:50pm
4:30am - woke up screaming and crying. Would not settle.
Being honest he has never been a great sleeper and I feel that I've never really got it right. I would really appreciate some advice. I think both me and the baby aren't very happy at the moment.
My partner does help out when he can but he works 6 days a week so isn't here a lot of the time.
As a final note, it does look like we have a tooth popping through but this is his seventh and with previous teeth it doesn't seem to have been too bad.
Thanks for reading this rather large post. Any help or empathy is very welcome.
