Right from what i can gather. OP hasnt bathed her baby in over a month because its cold. She hasnt bathed in a week because shes waiting for a parcel ]hmm]
And her partner hasnt bathed in over 2 weeks because he is lazy 
You have no money to buy a fan heater (£20 in Tescos) but yet you have just bought a PS3 - a PP quoted what you had wrote on another thread that after everything paid over you have over £2k in bank
i dont get that in a 2 months so thank yourself lucky?!
You then said you dont have no money because your partner cant fill out the Tax Credit form? Pick up a pen and do it yourself
Everyone on this thread was

until someone pointed out
Oh i think OP might be suffering from PND.
Im sorry but i had bad PND for 18 months - which started after the birth of my 1st son, i lived in a 1st floor flat that was fucking freezing, my auntie gave us a oil heater to use and it was that cold it didnt make a blind bit of notice - when it was icy the windows would ice up inside. I had PND then (but covered it up) but i still managed to bath my son. I placed the oil heater near a chair in the landing of the flat with the baby towel over the chair so the heater would warm it up. Worked a treat to keep my young one warm til he was properly dressed.
As for you getting a bath, why can you not have a bath when you partner is in the house then if the parcel comes - he can get it.
As for your partner not getting a bath, wel lets hope he doesnt expect oral sex anytime soon eh!?
